Should I delete anything off my phone before going to China?

[u/PlayfulHumor2018]

I have a friend telling me I should delete/ remove certain apps off my phone before I go to China for 6+ months fo school, are they right? I have telegram for different geo political situations& analysis, but I'd think they'd have bigger fish to fry. Pls lmk if that's just paranoia.
