How to set the expressions commonly used on WeChat recently?

Recently, the commonly used facial characters on WeChat cannot be set manually. This function is intelligent, and it can record the latest and highest frequency facial characters when we use WeChat facial characters, which is convenient for us to visit. I take the latest version of WeChat 8.0.29 as an example, and the specific steps are as follows:

1. Open the WeChat group chat or personal chat window, and click the "smiley face" icon in the lower right corner (as shown below):

2. Then a row of Yan characters will appear at the top of Yan characters, which will be displayed as "Recently Used". These are the frequently used and recently used facial expressions (as shown below):

Having said that, in fact, careful friends should be able to notice their usage habits, and those expression packs are always used more. For example, I like to use "in distress situation" very much, but I hardly need to smile. My sister likes to use "smile" very much. This is a common usage habit of a person.
