Ask an experienced person how to talk to her father-in-law (her father is a girlfriend now) under his guidance.

The most important thing is sincerity. Everyone wants their children to be truly happy.

Hello, uncle, I am. . . (Write your name here) I took the liberty of sending you this short message. I really love your daughter XXX and want to be with her forever. I am a girl. . . I want to visit your home on National Day. I wonder if you can agree.

See how his father responds to you, and then play it by ear.

For example, her father said that you are still young, and we can talk about it later. Wait, you can say that I can wait, and I believe my sincerity can be recognized by you.
