18 pm. According to the information of Du Shi's cultural tour of the Yellow River, the performance of the Yellow River Du Shi Night Market began on 18pm, including Zhang Qian cruise, Xuanzang westbound, flying pipa dance, etc., providing visitors with immersive experience projects. Night markets appeared in big cities in the late Tang Dynasty. During the Song Dynasty, the rulers explicitly allowed night markets. In the Northern Song Dynasty, Tokyo (now Kaifeng City, Henan Province) now refers to a market that mainly trades at night, selling groceries, snacks and games.
