Five days is enough. In November, 16, I also started from Shenzhen North to Guiyang North. I went to Qianhu Miao Village first, and then to Huangguoshu Waterfall. Seven little arches. No. ; Don&;t go. Transportation is basically based on trains. I feel that the train there is much more convenient and cheaper than the bus! Another suggestion is to pay attention to the local weather forecast, because if Huangguoshu Waterfall has sunshine, a rainbow will be more beautiful! Personally, I suggest you decide on the scenic spots to visit first, and then check the routes and traffic. To tell you the truth, with a mobile phone in hand now, transportation and accommodation are no problem!
