Adult content and things like making biological/chemical/nuclear weapons are the other main topics that usually get censored. I don’t think the Chinese models tend to be less censored than western models in these dimensions. You can sometimes find “uncensored“ models on HuggingFace where people basically finetune sensitive topics back in. There is a finetuned version of R1 called 1776 that will correctly answer Chinese-censored questions, for example.
