What are the most crowded places in the city?

Hello, I think this question is very long, but I still have to answer it.

There are shopping malls, supermarkets, parks and other places where people dance square dance, as well as children's playgrounds. Don't forget to eat. At present, there are many people in restaurants and supermarkets, but they are not paid much attention to. You can do activities in these places to distribute leaflets, posters, exhibition stands, gifts and so on. The premise is to let them add you to WeChat. The purpose is to let them add your WeChat friends, prepare more mobile phones and micro-signals, and add them separately. If the same one is added more, it will be full and may be blocked. After you have a few micro-signals, 1-2W WeChat friends, it will be easier to get started after operating in the circle of friends.
