A bookstore chain(连锁书店), “Popular Bookmall(大众书局)” introduced their unique style of book distribution(分布) in Shanghai back in November. This experimental store offers books at very low prices, and there is no staff(职员) to require shoppers to pay before taking books away. Sounds like a book lover's paradise(天堂)！
Popular Bookmall had already set up such a shop in Nanjing. The organizers of the Nanjing store report that it was a great success, enough shoppers voluntarily paid for their books. But most older “honesty stores” in China did not receive enough honest shoppers. For example, a shelf-service restaurant opened in Fujian province years ago which allowed shoppers to pay whatever they chose, but about one –fifth of shoppers paid nothing. Therefore some people have speculated(推断) that Chinese are becoming more honest. The organizers of the “honesty stores” say that their goal is to encourage people in China to remember how important honesty is.
Many are cared about dishonesty in China. Even at Popular Bookmall, not everybody choose to pay for their books. How can we encourage ourselves to be honest? We should listen to our conscience(道德心). This has deep roots in Chinese culture. Confucius(孔子) taught Chinese to be conscientious and honest.
But there is also a great rational(合理的) reason for “honesty stores”: the more honest people there are in society, the more reasons we have to trust others. And if people trusted each other, they'd be more willing to share. We could contribute to a “sharing economy” where you do not have to think about saving or spending money all the time, but helping other people. For all these reasons, society is built on trust, not only trade.
