The bus from Guangzhou South Railway Station to Dongguan Liaobu, to be exact, goes to Dongguan Liaobu Pedestrian Street.
There is a shuttle bus from Guangzhou South Railway Station to Dongguan East Bus Station (Liaobu). After arriving at the East Station, I can take bus Liaobu 6 to Fushan, but I took bus Liaobu 6 to Fushan a few years ago. At that time, I seemed to go to the commercial street. Now I'm not sure. Please ask before boarding. If not, you can take bus No.201or bus No.0 103 at East Station.
