Recently, online hike-sharing has become the new favorite in China. In major cities, bikes in, yellow, orange, blue, white and green, can be seen almost everywhere on the street. It seems that these bikes appeared suddenly, adding a new beautiful scenery to Chinese cities.

    Both the market and the public welcome online bike-sharing, but is it really a promising business? Well, it depends. After all, online bike-sharing platforms can never get away with huge operating cost and uncertain government policy.

    Some theorists might say that online bike-sharing platforms can earn a fortune simply through deposit. Since users will always need to rent bikes, their deposit will always be kept to online bike-sharing platforms.

    However，although online bike-sharing platforms may be able to use the deposit for other purposes at the primary stage, they will have to set up a special account, so that the deposit shall be used specially for its designated (指定的) purpose. As the market gets increasingly mature, they will have to do so whether to be responsible for users or in consideration of possible government regulations.

    Now that online hike-sharing platforms can，t make profit through deposit，how can they become profitable as fiercer market unfolds? Although Hu Weiwei, CEO of Mobike, stated in an article that she would take Mobike as charitable(慈善的) project if she failed, running a startup is absolutely different from managing a charity organization. After all , she has to pay back investors' billions of investment(投资).

    To make profit, online bike-sharing platforms might have toincrease rent fee for each trip, just as Didi did

    From this aspect, it might be a really good business. If we consider full screen ads fee, recommendation fee for business owners, etc. , its annual income might reach at least RMB 15 billion. If we consider the huge operation cost, including bike repairs，bikes' service life and labor cost, there might not be much net profit left. After all, offline operation cost has always been an unbearable burden for such internet plus mode-based startups.

    You need some bread and milk. But half an hour later, you leave the supermarket with a trolley（推车）full of food. What games do supermarkets play to make us spend so much money?

    The tricks usually start before you walk in. Outside the supermarket entrance, anybody who walks past can smell warm, fresh bread. That makes us hungry and ready to buy lots of food, not just bread.

    Now you're inside and, of course, a small basket would be fine, but all they have are trolleys. And of course the problem with a trolley is that it looks sad and lonely with just one or two goods inside. So we may fill it with something. In fact, supermarket trolleys are actually getting bigger so that we buy more.

    Of course, many people shop in supermarkets because they think everything is cheaper than in other shops. So supermarkets offer very cheap prices on some things but then have higher prices for other goods. One new trick is to put red stickers（标签）on them. Customers usually connect red stickers with lower prices so the red stickers is easy to be seen, even when there is no reduction! Interestingly, this trick appears to work more with men than with women.

    There is a story behind the position of everything in the supermarket. The most expensive goods are usually at eye-level so you see these immediately. The exception is anything that children might like. These goods are on lower shelves so that kids see them.

    Apart from what you see and smell in a supermarket, what about what you listen to? In most supermarkets they have soft, slow music. It's so relaxing that you slow down and spend more time (and money) in the store. Experts suggest it's better to shop when it's quieter, on a Monday or a Tuesday for example. And be careful with queues at the checkouts（收银台）. These are sometimes on purpose, to make you buy something from the checkout shelves while you wait.

    So, next time you go into your local supermarket, remember these tricks and see if you can come with just the things you went for.

    Why do Americans struggle with watching their weight, while the French, who consume rich food, continue to stay thin? Now a research by Cornell University suggests how life style and decisions about eating may affect weight. Researchers concluded that the French tend to stop eating when they feel full. However, Americans tend to stop when their plate is empty or their favorite TV show is over.

    According to Dr. Joseph Mercola, a health expert, the French see eating as an important part of their life style. They enjoy food and therefore spend a fairly long time at the table, while Americans see eating as something to be squeezed between the other daily activities. Mercola believes Americans lose the ability to sense when they are actually full. So they keep eating long after the French would have stopped. In addition, he points out that Americans drive to huge supermarkets to buy canned and frozen foods for the week. The French, instead, tend to shop daily, walking to small shops and farmers' markets where they have a choice of fresh fruits, vegetables, and eggs as well as high-quality meats for each meal.

    After a visit to the United States, Mireille Guiliano, author of French Women Don't Get Fat, decided to write about the importance of knowing when to stop rather than suggesting how to avoid food. Today she continues to stay slim and rarely goes to the gym.

    In spite of all these differences, evidence shows that recent life style changes may be affecting French eating habits. Today the rate of obesity — or extreme overweight — among adults is only 6%. However, as American fast food gains acceptance and the young reject older traditions, the obesity rate among French children has reached 17% — and is growing.
