Adults, how to deal with parents' excessive concern?

When I was a child, I listened to my parents, and when I first took the college entrance examination, my parents said, "Don't take the test, and I won't be allowed to take the test, and I'll die if I don't take the test by three points. When I was in the army, my parents said they wouldn't allow me to go to the military, and they said that I would not allow them to go, and they said they would not allow me to go to the field for a long period of time because I had not been allowed to go there, so they said that they wouldn't go out, and they wouldn't be able to go home. The parents said that if they went out, their hearts were not in the house, and it was like not having this son, so they didn't let them travel far away. Now, I have become a grandfather, and I will never interfere in the children's affairs, and I never felt bad about what my parents did at that time, and now I feel good about it. As long as you're contented there's no complaints. You don't need to get rid of it, you just need to someday, tell your parents that I did such and such a thing, have done it and continue to do it, and the reason why you are telling them is because you want them to know, and as far as the rest is concerned it doesn't matter.
