What's the matter with adding half an expression pack after receiving a reply in WeChat?

In WeChat, adding half an expression pack after replying to "received" is an expression, indicating that you have received the message from the other party, which has a certain emotional color. This expression is used between relatives, friends or colleagues to express a cordial or friendly attitude. For example, if the other party sends you a photo or sends you a text message, you can reply "Thank you!" Or "Roger that, OK!" Wait, add a smiling face or other expression pack to show your attitude and feelings. Of course, this expression also needs to be chosen according to specific situations and occasions, so as to avoid being used in inappropriate occasions.
