1, observe the circle of friends: if it is continuously updated within one month and the content is diversified, it may be large. On the other hand, if the content of the circle of friends is small or not updated, it may be a minority.
2. Check WeChat ID: If the default English characters have not changed, it may be small. Because tuba generally has its own unique ID, and trumpet may not care much about this.
3. Try to transfer money: send a penny to the other party for transfer. If the other party's account can be received normally, it may be real-name authentication, bound with a bank card, or it may be a large amount.
4, chat test: chat with each other every few time periods, if the other party replies in time, it may be big. Because the trumpet may not be used often, the reply may not be timely.
