I believe China doesn't hate bitcoin. China might hate the fact that it's untraceable, and with the problems that rised with the ICO's where many investors were scammed, and lost money, they couldn't do anything to retrieve that. It's a risky market, some will opt out of it, some will just act that they will opt out, and others will continue following bitcoin!
China have a communist government, so they want to take control all the aspect of economical state inside their country. And we all know that Bitcoin is a form of crypto-currency which is likely to happened to be a unreachable, uncontrollable form of currecny. Meaning that the government or their government will no longer have a control on investments , property and transaction of their people.
