1983, what method did Shenzhen try?

1983, Shenzhen tried to operate some businesses without food stamps by using exchange vouchers.

In the early days of reform and opening up, China's socialist market economic system construction faced many difficulties and challenges. In order to promote market-oriented reform, Shenzhen has tried a series of new mechanisms and policy measures.
