Yeah, I think it's a scenario where you can probably sue and you can probably win - but then (just like in the US) you're known as the person that sues their employer and it's a black mark.
I haven't heard of people getting lawsuits about 996 thrown out in China - but to be fair I also haven't heard of people suing over that either.
