1, the urban management of the night market may not be in that hut. You must go through the relevant formalities before he can let you go. Of course, you can also go directly, and then people there will take the initiative to come to you. It is more difficult for you to find them, but it is easier for them to find you.
2. There are some rules for charging, but they usually have the final say. You will say something, maybe less, or you can pay the receipt only once twice, and then find an acquaintance or something, which can be cheaper. Usually in the night market, you will receive long-term money, and this position is yours. Then you don't want to work, you are giving it to someone else. If you want to find a place to work, you can also share a booth with others, so you can be said to be relatives. How appropriate it is for you two to share the money equally, and in general, the other party has already paid the money.
3, usually after 3 pm, it depends on whether you close the stall or not.
The night market of Wanghua Street and Leifeng Stadium has a large passenger flow, and the charges are cheaper than those of South Station, but they are all paid in one season. If you are on the street from Wanghua Street to 700, it is not a night market stall. The day you let them see it, they will charge you, and if you don't see it, they will pull it. Of course, they are not allowed to set up stalls under strict management!
Good luck!
