Do you need to say anything when you visit your parents' graves for the first time?

We look at other people's things, burn paper, and talk to our late parents-in-law, saying that you will come to see them, introduce yourself and talk about the situation at home. Everything is fine. Don't worry, you're fine there. Burn them some money, don't be reluctant to spend it. If you have wine, give it to your parents-in-law. If you are sad, cry.

It's just normal. It's just that Yin and Yang are separated and can't interact.
