Living by the mountain, blending with the landscape is a symbol of not eating human fireworks, but practicing Taoism once again and understanding Zen, only then can the dust die and live in seclusion in the mountains.

Practicing in the world of mortals, being born, becoming a monk at home and getting rid of worldly things are the real great hidden and true practices.

There is another saying.

Tao Yuanming said, "When you ask a gentleman what he can do, his heart is far from self-centered." It means why you can be quiet and complacent in a noisy downtown, because your mood is far away from the downtown, so you can get quiet, and noisy places will be very remote.

There is also an allusion to the "Southern Shortcut". Then, this is official knowledge, and concealment in the mountains is concealment; Wandering in the streets and officialdom is also hidden, and it is a great hidden.

I agree with the first one.
