How to reply to a son-in-law's short message?

XX (son-in-law's name), considerate, send me a text message during the New Year. I also wish you a happy new year and stay with XX (your daughter)!

Just work hard, not too hard, and remember to take XX (your daughter) out to play often.

Go home and play when you are free.

I wish you and XX (your daughter) a long and happy life.

It makes him very happy that you say this, which is a perfect answer, because you said first that you should work hard and remember to go out to play more. Young people don't like their elders urging them to work hard because they feel tired and stressed. If you tell him to play more, he will thank you for understanding him and will work harder. And I wish him and your daughter happiness, which indirectly means that you agree with him, agree with him, and he will be very grateful to you, so this is the best answer.
