What do you say when you go to your mother-in-law's house on New Year's Eve?

Thank you for inviting me, because I am a woman and don't know much about men's psychology. My understanding is that when I go to my mother-in-law's house for the New Year, what I want to say most is to make her happy and say some good wishes. For example, you can say to your mother-in-law, mom, you are getting younger and younger, and this dress looks good. Give your mother-in-law a red envelope, and your son-in-law will honor you and make her happy. Because both women can understand women's hearts, women are actually very easy to coax, buy some clothes and jewelry, say a few nice words she likes, and women will be on cloud nine. The more a mother-in-law looks at her son-in-law, the more she likes him. He is also a half son. As a son-in-law, you should be sweet-spoken, diligent, wink, or humorous, which may coax your mother-in-law around.
