In fact, there are quite a few such trucks. You can search on Taobao in JD.COM. There are many kinds and prices are different. I just saw one. I don't know if you need this type. The pictures on this map are very convenient. Girls can just push, and it's not tiring and has a lot of load. There is also a girl who wants to set up a stall in a crowded place, otherwise it is really hard to sell. Now there are many stalls where you can make a small video of your fleshy body and send it to friends and online. People will come to you when they see it. Best wishes, I hope to adopt them.
