The circle of friends generally refers to a social function on Tencent WeChat. WeChat version 4.0 was launched and updated on April 19, 2065438.
Users can post words and pictures through friends circle, and share articles or music to friends circle through other software. Users can "comment" or "like" a friend's new photo, while other users can only view the comments or likes of the same friend.
There is a hidden switch in the WeChat settings-the circle of friends is visible for three days. Usually, this hidden setting is rarely used because most people are lazy. More than 1 100 million people have established a circle of friends visible for three days. This switch is used most in WeChat. This function is a very effective self-defense mechanism.
