People and boundaries
Family is the one audience you cannot leave the room on. The concern is real, which is what makes it expensive to refuse: the same person who is overstepping has also been kind to you for twenty years, and both facts are true at once. That is why the usual advice fails. You are not trying to win an argument with someone who does not think they are in one. You are trying to make one topic stop recurring without making the relationship the subject. Short, warm and repeated is the only combination that survives a second visit.
Pick one and make it yours

Open “Chinese original” for the Chinese text and pinyin, or “Why it works” for the meaning and wordplay.
Thanks for caring. I have my own plans for that.
When concern turns into involvement.
谢谢你关心，这事我自己有安排。
Thanks are given for the concern and the plan is declared already made. That closes the door on help without denying that the concern was real.

I’m not going to judge them or comment on this.
When you are asked to take sides.
我不评价别人，也不评价这件事。
Declining to comment removes the material the question needs. The doubled structure covers both the people and the event, so there is no gap left to press on.

Intensity depends on tone, context and who’s listening.
Thanks the concern and closes the door. Do not use it if you actually want their help.
Refuses to take a side. In a family fight this will be heard as taking the other side.
Both of these look like the obvious move. Both hand the conversation back to the other person.
“I’m an adult.”
It argues about status, which is the one thing a parent will not concede inside an argument. The topic becomes your maturity and stays there.
“You always do this.”
The word always turns one remark into a case file. Now the conversation is about the pattern, and you have to prove it, in front of everyone.
Keep the relationship warm while making your answer short enough to repeat at the next visit.
Same problem, different room
Keep private information private with a brief reply that gives the question nowhere further to go.
Thank the intention, refuse the instruction, and do not explain the refusal.
Close the topic without rejecting the person, and leave the next subject open to someone else.
