can we get to ethnic village Kunming by metro? I see a metro station named "west hills"

Do you mean the ethnic village in Western Hill? Then you need to go to this mountain area first. I find that you can take metro line 3 to Western Hill Park station, which is 1.7km away from the scenic area. You should walk towards south after exiting the subway station. If you don't want to take cable car, you can walk along the path.
