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.
