I am sure that China is a very difficult country for starting a business. In my opinion, you'd better start with business in Hong Kong. This is beneficial from any point of views. One more advantageous fact is that accounting services are cheap and of high quality in this place.
I think that in this situation it is better to use special services like https://wow24-7.io/e-commerce which is a really good help in order to boost the business. I really like that I can freely develop it with this company in order to attract new customers. The price is also pretty affordable, so I can freely get a perfect service and also to ask all the questions within a short period of time as well. The customer support is also a big plus for me.
