Making group purchases of famous local products and cosmetics (化妆品) with co-workers has become a common habit for the nine-to-fivers. But if your impression of group buys is still a piece of paper being passed around the office, everyone writes their details down, or endless phone calls or faxes to the supplier, then I’m sorry to say you’re behind the times. The popular way to make such purchases today is to get on line, form a special “group” and shop together. Not only can you save money by getting the best discounts, but it’s also a great way to meet new people.
“You could cut off my clicking finger and I’d still keep shopping this way!” so goes a common comment left by customers of China’s famous e-commerce website “Taobao”. Some even refer to group purchasing as a “path of no return”, saying that “Once you’ve tried it, you’ll get hooked!”
The origins of this new trend can be found in China’s well-known online consumers’ BBS, 55BBS, and the shopping boards. Since most BBS users are “white-collared workers and students who live in concentrated areas, buying clothes, food, and so on as a group saves on delivery costs as well as – if they meet the seller’s criteria (标准) – earn gifts, discounts, and frequent shopper points.
Users of this online group shopping boards purchase a lot of different items, from Japanese and Korean style clothes and Ugg boots, through fake eyelashes (假睫毛), stockings, food seasonings (调味品), and kitchen knives, to cosmetic masks and online college courses. All kinds of things have people coming together in groups to buy them, and the pickups are often organized on college campuses or office buildings.
Internet observer Liu Chenxi points the purchasing behavior that these online groups’ power creates a “team” effect. Unlike e-commerce sites driven by individuals’ purchases, sites that create this team effect have users that come together to achieve a common goal. The Internet has made this joining of forces to form group buying power possible, and it continues to snowball all around us.

People who enjoy a dream-filled sleep are better at recalling information and making links between facts when waking. But recharging with a shallow (小睡) offers no such mental improvement, the research suggests. The results of the study added to the growing body of evidence that Rapid Eye Movement (REM) sleep is very important to the brain’s ability to form strong memories.
An average night's rest includes four or five spells of REM sleep, but these bursts tend to be lengthier towards the end of the night. This means adults getting less than the recommended seven to eight hours a night -- and therefore inadequate REM sleep -- may be damaging their mind's ability to memorize: Although REM sleep is not classified as a type of deep sleep, it is only reached after the brain has passed through deep sleep stages.
In the recent study, participants were shown groups of three words and asked to find another word that can be associated with all three words. They were tested once in the morning and then given the same task again in the afternoon. In between, some were allowed a nap with REM sleep, some a nap without REM sleep, while the others had a quiet rest period. The quiet rest and non-REM sleep groups didn't improve, but the REM sleep group improved on their morning performance by an average of almost 40 per cent. Dr Sara Mednick, a sleep researcher at the University of California who led the study, believes the formation of connections between previously unassociated information in the brain occurs during REM sleep.
It is believed that sleep acts as a sort of mental filing system, enabling the brain to sort relevant information from useless information. This process may take place as memories are removed hem one art of the brain to others.
