北京动物园
In China, the existence of street and wet markets has been known for centuries, however, many of these were restricted in the 1950s and 60s and only permitted to re-open in 1978. The distinction between wholesale and retail markets is somewhat ambiguous in China, since many markets serve both as distribution centres and retail shopping venues. To assist in the distribution of food, more than 9,000 wholesale produce markets operate in China. Some of these markets operate on a very large scale. For example, Beijing's Xinfadi Wholesale market, currently under renovation, is expected to have a footprint of 112 hectares when complete. The Beijing Zoo Market (retail market) is a collection of 12 different markets, comprising some 20,000 tenant stall-holders, 30,000 employees and more than 100,000 customers daily.
