If you want to expand your circle of friends, the most effective way is to mix communities and pay. The paid community is full of people on the same frequency as you. Give out red envelopes first and introduce yourself (self-introduction is very important, so you must show your advantages and help others). Be sure to chat more in the group, and be sure to be conducive to her thinking. Only in this way can you attract people with the same frequency to add you. Secondly, you can also expand your circle of friends by sharing information. There are good resources that everyone can enjoy, which not only helps others but also expands themselves.
