Ye Shi are night markets in the evenings in China, and in Taiwan.
The markets run from sunset till about midnight, with lots of small vendors selling prepared foods ready to eat. The food can be eaten standing or walking or at tables with red lamps.
Early in the evening, the carts and trucks arrive and set up. They may also set up tents and tables.
They may sell other consumer goods as well, and there may be dancing groups.
In some places, there may be permanent stalls, such as the Night Market off Wang Fu Jing Street in Beijing.
Food sold may be served in wraps, or on plastic plates or in plastic bowls.
