What do all the expressions in WeChat mean?

Similar to QQ emoticons, using small pictures to express people's emotions and moods makes chatting monotonous. Some expressions can express people's emotions, such as emotions, joys and sorrows, better than words, and make chatting more interesting.

Next to each expression, there is a small word to express the meaning. After clicking the expression, the meaning of Chinese characters will be displayed in the dialog box. According to the avatar expression, it will automatically explain after a few seconds.
