Isn't Bitcoin trading and mining banned in China? Miners have moved from that country due to legal complications, so I don't think it will enable you to create PoW-based cryptocurrency.
If you want to create a currency better than Bitcoin, perhaps start by solving the problems of Bitcoin. Bitcoin is open source, you can see everything, and there are problems such as scalability, increased fees, and delayed confirmation times. If you succeed in solving it better than Bitcoin, there will inevitably be a demand for your currency, but unfortunately there are thousands of cryptocurrencies.
