If one is planning to visit China especially with a wheelchair, I would recommend getting a guide purely to act as a translator unless you can speak fluent Chinese!
Despite people’s preconception of China, it has been one of the best countrys that I have visited in terms of how accommodating people, are especially to people with disabilities, for example that guy in Xi’an who held up the restaurant menus for me whilst I read it and our guide in Beijing, China has almost no system set up to help disabled people, however, it is clear that, as a society, they are very much trying to become an inclusive country, even if one has to hunt around for ages to find a ramp!
