Not these days. These days hospitals are legally required to save your life if they are able. However, that won’t stop them from sticking you with crippling debt afterwards. Which, has lead to people taking their own lives.

Late reply, didn't see this post before:

This is actually a common plot point in a lot of Chinese dramas. Like there's a character that need an emergency life-saving surgery but the hospital requires the next-of-kin to pay a large amount money first, which they cant afford, but then they have a rich relative they haven't talked to in a while, so they frantically try to find their phone number / address and try to get in contact. It's kinda so overdone, like it's the "cliche" of Chinese drama.

Not sure if this is still a thing anymore, but there is no laws in China that requires hospitals to treat you if you can't pay.
