Set up a stall, hehe, actually it doesn't cost much. After you let it go, someone will come to you. Of course, the stall fee is charged. Generally, it is collected by the security team, and the price ranges from 5- 100 yuan! I used to put it in Xili's place, charging 5 yuan during the day and recharging it at night, just like 5 yuan! Some places charge according to your floor space! (I hope it can be adopted in the end)
