When do those markets in Shantou city buy the most food, when do they buy the least food, and when do they close?

Now Shantou's population and economy are moving eastward, so the market in the old city in the west is much less popular than some markets in the east. Shantou's farmers' market is represented by the North Market of Longan, with a wide variety and everything. The general market is from 7 am to 12 am and from 4 pm to 6 pm. This time is the most crowded time. 1 at noon, 2 o'clock is when there are few people.
