Many young people believe shared bicycles have many advantages. They are not expensive to rent, they do not have to be protected from thieves, and there is no need to repair them. You just have to change them for another one. They are also environment friendly and lower the use of cars, which also helps to relieve traffic. In fact, it is considered an awesome（可怕的） combination of technology and tradition.
Since they appeared, shared bicycles have raised a lot of dust. There is no doubt about the benefits but the disadvantages cannot be ignored. Many problems related to shared bicycles have appeared. It is not only due to bad behavior from some users who always want to seize the bicycles, but also because of the mess that has been created since one can leave the bicycle anywhere, which is against public urban order management. There are so many poorly parked bikes that sometimes they end up blocking streets.
In Xi Luo yuan, Beijing, the “Civilized Use of Bicycles” campaign （运动）has been launched. In addition to having 40 officially permitted stops, there are also clear signals（信号） to lead users to these stops. A team of supervisors keep order in the area. This is the first area that is part of an official system to manage bicycles. The purpose of this campaign is to solve the mess that the popularity of shared bicycles is causing in Beijing, both with the participation of companies and the users. If the pilot plan works out well in Xi Luo yuan, it will be extended to all of the cities in China.

Advertising plays a major role in the competitive business world. Many industries take advantage of the power of advertising to attract or to win customers away from their business competitors. The influence of advertising is so huge that it causes many people to buy things that they don't want at the start.
Advertising encourages people to buy things they don't want through misleading ideas. Advertising is proven to be a successful tool to stress the features of their product to the public even though it's regarded undesirable such as cigarettes，drugs，alcohol and so on. For example，Dunhill，a cigarette company which sponsors many football teams，seems to be promoting cigarettes to the public. Without the sponsorship，the company will be less known to the public，resulting in fewer sales of cigarettes.
Besides that，advertising has a large influence on the decisions made by the people in their everyday life. Many businesses use advertising as a form of promoting to create awareness about their product in the market. For instance，in a fast food industry，the introduction of a new flavor of burger needs advertising to reach the public while the other burgers require advertising to increase sales. Children，especially，are easily influenced by advertisements and will have the desire to dine at fast food restaurants after that. Although fast food is bad for health，it has successfully become appealing to the public through advertising.
However, advertising plays a part in helping customers to compare a product in terms of price, quality, reliability and so on. Without advertising, it will be very difficult for customers to judge the worthiness of a product. For example, advertisements published by various companies have given the customers the opportunity to choose wisely when they are purchasing an item. Without the power of advertising, customers will be stuck to a brand which may not offer the best choice.
