Method 1: There is a search in your QQ interface. Click enter, and then click advanced search. There is your province. The disadvantage is that some people's information is inconsistent with their location, so some people may not be in the same city as you.
Method 2: There are QQ groups in your QQ interface (or just click on the group users in the search bar to search). Click enter, then click I want to join a group, select the same city in the category, and then select the name of the province and city you want to find, which contains many QQ groups of the city you choose. The disadvantage is that some QQ groups have requirements such as the number of people, so they may not be able to join, and they have to wait for the review of the QQ group Bambusa.
Method 3: You can register as an ordinary member in QQ friends, so you can chat with people in the same city. The disadvantage is that registration is a bit troublesome, but the people you are looking for are basically from the same city, and if you register as a senior member, you can enjoy many functions, such as taking pictures.
You might as well try them all and see which one suits you. Personally, I think the third one meets your requirements. I hope you can find friends in the same city.
