What particular place does the lianhuachi long distance bus stops at wuhan? Is it nearJi Jiadun?

I want to ride a bus from beijing to guangzhou.but there's no bus going there. so i think that beijing-wuhan then transfer to guangzhou is possible.however im not sure if the bus stop from beijing is very far from the bus station going to guangzhou. may i also know how much money do i need to get to guangzhou by bus?
thank you :-)
