Dear Josey,
if I want to make the same route but starting from Feng Huang, are buses so frequent?

Do you mean the bus schedule from Fenghuang to HH West Bus Station?
If yes, you can take a coach from Fenghuang General Passenger Transport Station on North Phoenix Road. The schedules are from 08:00 to 18:00 with the frequency of around an hour.
