If I want to study abroad, I will go to university in China after getting a green card, and then how can I prove that I have lived in the United States for one year so as to get tuition remission from public universities? Are you talking about the grants for tuition remission in public universities? You can apply for a grant, but you have to prove that your income is below the minimum standard, and FA will not give you a tuition-free university in China.

Also, if you are a green card, if you are in China all the year round, the United States will not let you renew your green card, or directly prevent you from re-entering, because green card holders cannot leave the United States for a long time.

Also, it is easy to prove that you have lived in America for a year. You hand in three materials, your housing contract and a copy of the rent payment, your mobile phone bill and electricity bill. This must be your name. You can't fake it, because the time and date of entry and exit are marked on your passport.
