Choose compact areas, stay long enough, and see villages outside peak tourist times. Plan according to local traffic realities; don't rigidly follow the city's rhythm.
Let community life dictate the tone
Ask before filming people, ceremonies, or private homes. When appropriate, directly consume to support the local area, and treat cultural spaces as living spaces rather than performances.
Leave room for the weather
Rain and fog are part of the mountain atmosphere. Flexible sorting gives them texture, not disappointment.
