Wechat has the function of cclean, but when using this function, we are required to download Tencent Mobile Manager from the mobile phone, so if we want to clean it up, we must use this software. Open Tencent Mobile Manager-"Health Optimization"-"Garbage Cleaning". After a while, you will find that the mobile phone housekeeper has scanned all the system garbage in our WeChat, such as WeChat cache, chat pictures and videos, and then cleaned it up.
