Is BTC legal in China?

I'm curious to know, is Bitcoin (BTC) considered legal in China? I've heard conflicting opinions about its status in the country, and I'm trying to get a clear understanding. Some say it's outright banned, while others claim it's just certain activities related to it that are prohibited. Could you clarify this for me? It's important for me to understand the legal framework surrounding cryptocurrencies in China before I make any decisions regarding investments or transactions.
