I am a person with low laughter and low tears. How can I improve my laughter and tears?

Watch more jokes and learn to be reserved (yes, watch more jokes, and what others say will be less funny. To be polite, laugh moderately. Talk more and learn to express (socializing can help you control your emotions better in front of others, including crying and laughing)

Read more books and gain profound knowledge; The more books you read, the more knowledge and insight you will have from a certain angle, and the better your grasp of emotions will be.
