A lemmygrad user actually made a thread about this a few days ago, about how they came back from China and they were super racist at them, questioned why they had communist literature in their bag and made multiple attempts to groom them with anticommunist talking points.

My favorite line was “Yeah China is repressive, but they never once tried to get me arrested for my thoughts” EDIT: Thread here

In communist China your shit get searched and you get interrogated when you reenter the country
