Is Bitcoin still illegal in China?

I'm a bit confused about the status of Bitcoin in China. I've heard conflicting reports about whether it's still considered illegal or not. Can you clarify the current legal status of Bitcoin in China for me? I'm particularly interested in understanding if there have been any recent changes in the laws or regulations regarding cryptocurrency in the country. Additionally, if Bitcoin is legal, are there any restrictions or limitations on its use? I'd appreciate it if you could provide a detailed explanation.
