Beijing's Mega Mall
by Rebecca Karnak
I do not usually enjoy shopping. In China—with the crowds, the multiple steps needed to check out, and the infinite choices of things to buy—I dread it even more. But when I heard that Beijing had opened the largest standalone shopping structure in the world, I had to investigate.
Until recently, Beijing's 6 million sq ft Golden Resources Shopping Mall was the world's largest. (Guangdong's 6.5 million sq ft South China Mall opened this spring.) Opened in October 2004, Golden Resources still easily tops the largest mall in the United States—Minnesota's 4.2 million sq ft Mall of America—as well as the largest mall in North America, the 5.3 million sq ft West Edmonton Mall in Canada. Today, China has more than 400 malls. Deloitte Research estimates that 7 of the world's 10 largest malls will be in China by 2010.
At the start of my investigation, I hopped in a cab near Beijing's Jianguomenwai subway station, and the driver sped up the Second Ring Road toward Golden Resources in Haidian District. After almost half an hour, the driver wound his way through the narrow, tree-lined streets near Beijing Foreign Studies University and entered a wide street lined with new apartments and office buildings. Approaching the mall as the driver did, I was not as overwhelmed by its size as I thought I would be. Golden Resources is a compact, five-story building with neatly arranged shops that run east-to-west. I paid my ¥40 ($5) cab fare and stepped inside.
My first stop was a jewelry counter, an island between rows of shops. I looked at a few mid-priced gray pearls and braced myself to be greeted by an overenthusiastic sales assistant. When no one approached me, I looked up to see a young female sales assistant at the opposite counter talking to her friends, presumably the sales assistants selling silver bracelets next door. Being ignored by the sales assistant was a refreshing switch from being accosted by pushy vendors at Beijing's Silk Market and elsewhere. The scene felt familiar, as if it could happen at a mall in Cleveland, my hometown.
But as I walked past watch shops, cafes, women's clothing stores, and plenty of advertisements for brands such as Gucci, DKNY, and Fendi, I realized that most of the other sales assistants weren't jumping up to greet the few customers strolling by on this late Sunday afternoon either. In a city of roughly 14 million residents, I expect crowds at most public places on Sunday afternoons. But after more than a half year in operation, Golden Resources has yet to attract the number of customers it will need to stay profitable. In fact, I turned one corner of the mall to discover two people playing badminton.
The stores in that section of the mall had not opened yet, and the couple was taking advantage of the open space.
Once I hit Toysmart on the fourth floor, though, I found signs of commercial life. Kids were running around, testing out scooters their parents had yet to purchase. Down the hall were two different playgrounds for children and their families that charged by the hour for jungle gym access.
The adult playgrounds are on the mall's fifth floor: Stellar International Cinema, which has seven screens, and the Century Club, a health and fitness center. Making my way back down through each level, I came across shops neatly arranged by product sold. I passed three consecutive shops selling treadmills, wondering which one would go out of business first, before entering an area of sporting goods stores. For the first time in Beijing, I found authentic North Face gear, and the Nike and Adidas stores also carried the real deal. Many of the products I saw, though, including the treadmills and the ¥32 ($4) fruit smoothie I purchased at a kiosk, are luxury items for the average Beijinger.
Golden Resources' 1,000 stores, 230 escalators, and 10,000 free parking spaces seem like nothing in comparison to its rival's facilities. Guangdong's South China Mall boasts theme parks, pyramids, giant windmills, a 1.3-mile river, and an 85-foot replica of the Paris Arc de Triomphe. These large, high-end malls might not be the most profitable model for China, however. Even though China's middle class is growing, and urbanites have more money to spend than ever, China is generally a country of savers.
According to the People's Daily, Chinese citizens have spent, on average, only 60 percent of their incomes over the past 10 years, while the world average has been 78 percent. Walking through Golden Resources makes clear that China either has too many malls or that prices are still too high for many customers. Most likely it is a combination of both.
Golden Resources has not attracted a large foreign crowd yet either, mostly because of the mall's location in northwestern Beijing outside of Third Ring Road—far from the city's foreign enclaves. I did not see a single foreign face or hear a foreign language in the hour and a half I spent shopping that Sunday afternoon. Moreover, none of the stores I visited accepted foreign credit cards. In contrast, in many stores at the Oriental Plaza and China World malls in the center of the city, no one bats an eye when a customer hands over a Visa card from a foreign bank.
But once the newly built apartments and office centers around the mall are occupied, Golden Resources will have plenty of Haidian residents to serve, including the many wealthy employees of China's Silicon Valley, Zhongguancun, and other Beijing districts. Currently, many bus lines run to and from Golden Resources, but the subway gets customers only part way there (shoppers must take a bus from the Gongzhufen subway stop). Under Beijing's 2008 subway plan, the nearest subway stop will be Wanliu, less than a mile away. When the new subway lines are completed, all of Beijing might flock to Golden Resources on a hot summer day, even if only for the air conditioning—or perhaps to show support for one more record-breaking Chinese achievement.

#1 World Largest Mall~~South China Mall in Dongguan, China
A Chinese billionaire made rich through his business in the instant noodle industry built the mall in 2005, and since then it remains almost completely vacant. Dongguan has a population of over ten million people, yet the mall is so large it could not be constructed in the downtown and had to be moved to a suburb and can only be reached through car or bus, which many people do not have access to.
After the first several years failed to attract shops, many simply stopped to even consider the mall as a realistic space for a shop. While it is mostly empty there are some shops that fill its massive space. In the closest area to the parking garage there are several fast food restaurants, yet little else. The mall does contain several amazing features including a replica of the Arc de Triomphe, Venice’s St Mark’s bell tower, canals with gondolas, and even an indoor-outdoor rollercoaster! Each section of the mall is modeled after a real city or region such as Amsterdam, Paris, Rome, Venice, Egypt, the Caribbean, and California!

"I Won't Give Up"
Hmmmm ... Hmmmm ... Hmmmm ... Hmmm ...

Confusing stars for satellites
I never dreamed that you'd be mine
But here we are, we're here tonight
Singing Amen, I, I'm alive

10 things you can do to help save the earth..lets do it together!!
- Save energy to save money.
- Set your thermostat a few degrees lower in the winter and a few degrees higher in the summer to save on heating and cooling costs.
- Install compact fluorescent light bulbs (CFLs) when your older incandescent bulbs burn out.
- Unplug appliances when you're not using them. Or, use a "smart" power strip that senses when appliances are off and cuts "phantom" or "vampire" energy use.
- Wash clothes in cold water whenever possible. As much as 85 percent of the energy used to machine-wash clothes goes to heating the water.
- Use a drying rack or clothesline to save the energy otherwise used during machine drying.
- Save water to save money.
- Take shorter showers to reduce water use. This will lower your water and heating bills too.
- Install a low-flow showerhead. They don't cost much, and the water and energy savings can quickly pay back your investment.
- Make sure you have a faucet aerator on each faucet. These inexpensive appliances conserve heat and water, while keeping water pressure high.
- Plant drought-tolerant native plants in your garden. Many plants need minimal watering. Find out which occur naturally in your area.
- Less gas = more money (and better health!).
- Walk or bike to work. This saves on gas and parking costs while improving your cardiovascular health and reducing your risk of obesity.
- Consider telecommuting if you live far from your work. Or move closer. Even if this means paying more rent, it could save you money in the long term.
- Lobby your local government to increase spending on sidewalks and bike lanes. With little cost, these improvements can pay huge dividends in bettering your health and reducing traffic.
- Eat smart.
- If you eat meat, add one meatless meal a week. Meat costs a lot at the store-and it's even more expensive when you consider the related environmental and health costs.
- Buy locally raised, humane, and organic meat, eggs, and dairy whenever you can. Purchasing from local farmers keeps money in the local economy.
- Watch videos about why local food and sustainable seafood are so great.
- Whatever your diet, eat low on the food chain. This is especially true for seafood.
- Skip the bottled water.
- Use a water filter to purify tap water instead of buying bottled water. Not only is bottled water expensive, but it generates large amounts of container waste.
- Bring a reusable water bottle, preferably aluminum rather than plastic, with you when traveling or at work.
- Check out this short article for the latest on bottled water trends.
- Think before you buy.
- Go online to find new or gently used secondhand products. Whether you've just moved or are looking to redecorate, consider a service like mudah.my or onlinerevo.net to track down furniture, appliances, and other items cheaply or for free.
- Check out garage sales, thrift stores, and consignment shops for clothing and other everyday items.
- When making purchases, make sure you know what's "Good Stuff" and what isn't.
- Watch a video about what happens when you buy things. Your purchases have a real impact, for better or worse.
- Borrow instead of buying.
- Borrow from libraries instead of buying personal books and movies. This saves money, not to mention the ink and paper that goes into printing new books.
- Share power tools and other appliances. Get to know your neighbors while cutting down on the number of things cluttering your closet or garage.
- Buy smart.
- Buy in bulk. Purchasing food from bulk bins can save money and packaging.
- Wear clothes that don't need to be dry-cleaned. This saves money and cuts down on toxic chemical use.
- Invest in high-quality, long-lasting products. You might pay more now, but you'll be happy when you don't have to replace items as frequently (and this means less waste!).
- Keep electronics out of the trash.
- Keep your cell phones, computers, and other electronics as long as possible.
- Donate or recycle them responsibly when the time comes. E-waste contains mercury and other toxics and is a growing environmental problem.
- Recycle your cell phone.
- Ask your local government to set up an electronics recycling and hazardous waste collection event.
- Make your own cleaning supplies.
- The big secret: you can make very effective, non-toxic cleaning products whenever you need them. All you need are a few simple ingredients like baking soda, vinegar, lemon, and soap.
- Making your own cleaning products saves money, time, and packaging-not to mention your indoor air quality.

How to spot fake LV(Louis Vuitton) Bag?
1. Know your bag!
Was it ever made by Louis Vuitton?
Try your
bag on at a boutique, check the VUITTON website, or Elux, buy a catalog-
etc, but make sure that the bag you are looking for was ever made by
Louis Vuitton. This is especially common in Multicolore bags- (there
was never an Multicolor Backpack, Ellipse, Papillon etc), Cherry
Blossom (no CB Speedy, Alma nor Cabas tote, Pegase), Cerises (no
Papillon, Ellipse, Cabas Piano, Mezzo or Alto) or vintage pieces.
Know its parts: What is it "supposed"
to be lined in? Should it have feet? What does the base look like?
Should it have a d-ring inside? Where? Does it have a date code?
Should it? Where?You can check the Vuitton website or your local
boutique for this information... you can also purchase more detailed
guides here on eBay that include such details... For example: If it is
supposed to be lined in brown cotton canvas, it needs to be lined in
brown cotton canvas. There have never been brown suede linings- even in
the vintage pieces. Alcantara kind of looks like a suede-y material,
but it isn't suede and although is found in a greyish mushroomy color,
it isn't found in dark brown. A Speedy of any age should have brown
cotton canvas lining, so if you see any other lining- you know it isn't
authentic. The lining of a Speedy has NEVER looked like this:
Know its Monogram placement: Louis Vuitton has been in
production since 1854! Their style is classic, and quality-
phenomenal! The traditional Monogram Toile canvas that is so popular
today- had its beginnings in 1896. The monogram itself can give clues
as to authenticity. Louis Vuitton is very careful about the way that
the monogram is placed on any piece. Most of its styles are the same
today as they were when they first came out- with a few exceptions. The
actual LV monogram is usually (with the exception of some vintage
pieces) symetrical from side to side in all monogram styles
(traditional, Multicolore, Cerises, Mini mono, Vernis etc.) as you can
see in this Louis Vuitton Speedy (notice where the LVs are in relation
to the handles, sides, quatrefoils etc)
Watch the stitching: Louis Vuitton is very careful
with it's stitching. Stitching should be very even and regular. The
same number of stitches will be found in similar locations on similar
bags... for example the leather tab that the handle attaches onto on any
size monogram Speedy bag will always have 5 regular, even stitches
across the top, like this:
Watch the age: While vintage pieces
follow most of the rules that I discuss in this guide, there are
definite differences in vintage pieces. For example, all French Company
pieces vary slightly... so if you are looking at a French Company
Vintage Vuitton piece, it may differ a bit. For instance, the FC Speedy
30 does NOT always have 5 stitches across the top, does NOT have upside
down LVs on one side, and does NOT have Louis Vuitton embossed in the
hardware. I'm currently writing a guide to help with these vintage
gems- so watch out for it.
Made in Spain? Yes, while it is true
that authentic Louis Vuitton is made in France, for over 25 years, Louis
Vuitton has also produced bags in the USA, Spain, Germany and Italy.
It is not true that a Louis Vuitton bag has to be marked "Made in
France" to be authentic. Here is the embossed markings of an authentic
Louis Vuitton bucket bag, Made in the USA:
What about the "Upside Down LVs"? People email me all
the time about this one... Some styles of authentic Louis Vuitton WILL
have "upside down" LVs on the backside. The reason for this is that
Louis Vuitton uses one continuous piece of leather that wraps around
from the front to back, without a seam on the bottom- and so, the
backside has upside down logos. This is true on the Speedy styles
(except French Company Speedys), the Keepalls, Papillons, and some
similar styles. Most monogram pieces (any piece with a separate piece
of canvas or leather on the bottom) will have the LVs rightside up on
both sides. Here is the backside of an authentic Speedy 25:
What about the patches? It is true
that many older fake bags had patches on the interior and exterior that
simply were never there on authentic versions. Fake exterior patch
followed by fake interior patch:
However, some authentic bags DO have them! This is
especially true of vintage pieces where there is a round patch meant for
personalized embossing like this:
Some current bags also have patches inside, like the Viva Cite:
The Fonts: Louis Vuitton uses a very specific font.
I've noticed that a few counterfieters have begun to do a better job at
knocking it off... so be careful, but current LV fonts will ALL look
like the one on the patch above. Notice the VERY round "O"s. Here is
an example of two straps- one authentic, one a "better" fake. Can you
tell the difference?

What does Jewel in Watches means??
Jewel bearings were invented and introduced in watches by Nicolas Fatio (or Facio) de Duillier and Pierre and Jacob Debaufre around 1702
to reduce friction. They did not become widely used until the mid 19th
century. Until the 20th century they were ground from tiny pieces of
natural gems. Watches often had garnet, quartz, or even glass jewels; only top quality watches used sapphire, ruby, or diamond.
In 1902, a process to grow artificial sapphire crystals was invented,
making jewels much cheaper. Jewels in modern watches are all synthetic
sapphire or (usually) ruby, made of corundum (Al2O3),
one of the hardest substances known. The only difference between
sapphire and ruby is that different impurities have been added to change
the color; there is no difference in their properties as a bearing.The advantage of using jewels is that their ultrahard slick surface has a lower coefficient of friction with metal. The static coefficient of friction of steel-on-steel is 0.58, while that of sapphire-on-steel is 0.10-0.15.
Why they are used
Jewels serve two purposes in a watch. First, reduced friction can increase accuracy. Friction in the wheel train bearings and the escapement causes slight variations in the impulses applied to the balance wheel,
causing variations in the rate of timekeeping. The low, predictable
friction of jewel surfaces reduces these variations. Second, they can
increase the life of the bearings. In unjeweled bearings, the pivots of
the watch's wheels rotate in holes in the plates supporting the
movement. The sideways force applied by the driving gear causes more
pressure and friction on one side of the hole. In some of the wheels,
the rotating shaft can eventually wear away the hole until it is oval
shaped, and the watch stops.
Types
- Pallets - These are the angled rectangular surfaces on the lever that are pushed against by the teeth of the escape wheel. They are the main source of friction in a watch movement, and were one of the first sites to which jewels were applied.
- Impulse pin - The off center pin on a disk on the balance staff which is pushed by the lever fork, to keep the balance wheel moving.
In bearings two different types are used:
- Hole jewels - These are donut shaped sleeve bearings used to support the arbor (shaft) of most wheels.
- Capstones or cap jewels - When the arbor of a wheel is in the vertical position, the shoulder of the arbor bears against the side of the hole jewel, increasing friction. This causes the rate of the watch to change when it is in different positions. So in bearings where friction is critical, such as the balance wheel pivots, flat capstones are added at each end of the arbor. When the arbor is in a vertical position, its rounded end bears against the surface of the capstone, lowering friction.

- While it only takes 8 minutes and 19 seconds for the light from the surface of the sun to reach us, it actually takes about 10,000-170,000 years for a photon to travel from the core of the sun to the surface.
- Once regarded by astronomers as a small and relatively insignificant star, the Sun is now known to be brighter than about 85% of the stars in the Milky Way.
- The Sun has an effective surface temperature of 5780 K, which is equivalent to just under 10,000 F and 5500 C.
- The core of the Sun has a density almost 150 times the density of water on Earth. The temperature at the core is close to 14 million Kelvins and Celsius degrees, or 25 million degrees F.
- About 3/4 of the Sun’s mass consists of hydrogen, with most of the rest being helium (23.8%) and about 2% remaining consisting of other elements such as iron, oxygen, carbon, neon, and a variety of others.
- The Sun generates its energy from nuclear fusion at its core fusing the hydrogen nuclei into helium. The nuclear fusion is self regulating; if the Sun’s diameter gets smaller while maintaining the same mass, the pressure at the core increases creating more nuclear fusion which in turn causes it to expand. If it expands maintaining the same mass, the pressure lessens in the core causing less nuclear fusion. So a natural equilibrium has resulted in this process with our Sun, though there are stars that can be observed going through this process of massive expansion and contraction at very steady rates.
- At the core of the Sun, nuclear fusion power produced is estimated at about 276.5 watts/m^3. Interestingly this power production is more equivalent to a reptile’s metabolic energy production than what we would think like a nuclear bomb.
- This is in contrast to the amount of energy per (W/m^2) deposited on the surface of the Earth from the Sun, which is about 1368 W/m^2.
- Each second more than four million tons of matter are converted to energy within the Suns core. At this rate, the Sun has so far converted 100 Earth masses of matter into energy. This will give the sun an effective lifetime as a main sequence star of about 10 billion years with about 5 billion years to go.
- The Sun does not have enough mass to go supernova and explode. However, in about 5 billion years it will enter a red giant phase steadily expanding until it consumes the Earth. But fear not, the Earth will already be dead in about 1 billion years due to the fact that the sun becomes about 10% brighter every billion years; so in 1 billion years the Earth’s surface temperature will be such that no liquid water will be able to exist unprotected on the surface of the Earth.
- The Sun orbits the center of the Milky Way at a distance of approximately 24,000-26,000 light years.
- The Sun completes a clockwise orbit of the Milky Way center in about 225-250 million years.
- The Sun is about 150 million km or about 93 million miles from the Earth; this is by definition one astronomical unit (1 AU).
- The Sun is almost a perfect sphere; its diameter at its poles differs from the diameter at its equator by only 10 km or 6 miles.
- The area of the sun we call the “surface” is really just the outermost layer that radiates a significant amount of light. There is actually quite a bit of the Sun above that layer.
- The Sun’s magnetic field is less than half of what it was just 22 years ago. This has shrunken the Sun’s heliosphere which helps protect the earth from cosmic radiation. Because of this, the Earth is now being struck with significantly more cosmic radiation than just a couple decades ago.

Why Zippers Have YKK On Them
Today I found out why zippers have a YKK on them.
The YKK stands for Yoshida Kogyo Kabushikikaisha (say that five times fast). In 1934 Tadao Yoshida founded Yoshida Kogyo Kabushikikaisha (translated Yoshida Industries Limited). This company is now the worlds foremost zipper manufacturer, making about 90% of all zippers in over 206 facilities in 52 countries. In fact, they not only make the zippers, they also make the machines that make the zippers; no word on if they make the machines that make the parts that make up the machines that make the zippers.
Their largest factory in Georgia makes over 7 million zippers per day.
In any event, Mr. Yoshida’s company zipped to number one by practicing the “Cycle of Goodness”, as he called it. Namely, “No one prospers unless he renders benefit to others.” Using this principle, he endeavored to create the best zippers out there that would hold up over long periods of time in the end product. This in turn would benefit both the manufacturers who used his zippers and the end customer and because of these things benefit his company with higher repeat and referral sales, thus completing the “Cycle of Goodness” *zen moment*
So next time you’re zipping up, take a moment to remember Mr. Yoshida; also, if you’re going commando, careful with Captain Winky on the zip up. I can’t stress that enough.
