Hi，from Hangzhou to Taiping Cable Car, you can take long distance bus from Hangzhou to Huangshan and then hire a van to Taiping Cable Car, since there is no direct bus from Tunxi or Tangkou to Taiping Cable Car. I would suggest you take the cable car from Tangkou, since the road on the north side of the mountain is not easy to walk and also you'll need to walk a long way to get to the cable car station. After visiting the Huangshan, you can then go to Hongcun and Xidi.
