1. airplane. Buy a plane ticket, depending on whether you are from Guangzhou or Shenzhen, the domestic line goes to Huaihua Zhijiang Airport, there is a bus station not far from the airport, and a bus goes to Huaihua. It takes more than 2 hours by plane+car. The fare depends on whether it is off-season or peak season.
2. the train. Buy a train ticket from Dongguan to Huaihua first, depending on whether you buy a ticket (there are two railway stations in Changping) from Dongguan East Station or Dongguan Station. Both stations have trains to Huaihua. It takes about 16 hours to get to changping railway station by bus from Dongcheng Bus Station (there are many buses to Changping). Hard seats range from 111 yuan to 151 yuan.
I hope I can help you!
