i know i said good things about this stock but I'm conflicted

$ACM Research (ACMR.US)$ i said a few weeks ago there are some things about this company that I like but then I discovered that majority of their revenue comes from China now that's a big concern for me because of the US chip acts I don't know if ACMR can continue to sell to Chinese customers unless they find loopholes but it's very concerning to me so I didn't start a position yet. I might do it purely from a technical analysis perspective but I have not pulled the trigger I have not bought any shares
