How to view micro-signal friends online?

How to check whether WeChat friends are online is as follows:

1.？ First of all, you can judge whether you are online or not by looking at the dynamics in WeChat discovery and the last time the other party sent a message. If there is an update, it proves that you play WeChat online.

2.？ You can also send messages to each other. If there is a reply, it proves that the other party is online. If the other party doesn't reply for a long time, it means that they don't want to reply, or they are just not online.
