Why is there an advertisement for playing mahjong in my WeChat circle of friends?

This is a friend circle advertisement pushed by WeChat (note: the friend circle advertisement cannot be closed). If you don't want to see this kind of advertisement, you can turn on the recommended personalized advertisement in the privacy settings. When this function is turned on, only advertisements that are more biased towards your preferences will be pushed. The following demonstrates the opening process:

Demonstration equipment: Red Rice Note 10 Pro, MIUI 12.5.5, WeChat 8.0. 16.

First, open the mobile phone WeChat personal center, and click Open Settings.

Second, find the privacy settings and click Open.

Step 3, turn to the bottom and click Open Personal Information and Permission.

4. Then click to open the personalized advertising management function.

5. Finally, open personalized advertisements, and then the circle of friends will only push advertisements that are biased towards their own preferences.
