I think that's fake news. Bitcoin and cryptos usage in China was never banned, what China banned are ICOs and shutting down of all exchanges. Cryptocurrency mining is still ongoing in China, and they're the number one seller of ASIC hardware worldwide.
I recently read that China has developed a two-year plan to completely ban decentralized crypto currency in its territory. The first stage of such a plan expires in June next year. An appropriate topic with a link is available in the news section on this forum. All the same, they decided to prohibit the crypto currency. If this happens, China will be completely isolated in terms of crypto currency from the rest of the world. It is a pity that such a large country with huge crypto-currency potential and such human resources will be kept out of the general development.
