1. Qu Yuan's "The Fisherman": "The fisherman smiled and walked away. The song goes: 'The water in Canglang is clear, and you can use it to wash my tassel; the water in Canglang is turbid, "You can make my feet dirty." Then he left and said nothing. 2. The Sixth Patriarch Huineng: There is no tree in the Bodhisattva, and there is no stand in the mirror. There is nothing in it, so how can it cause dust.

3. Shu Huyin's Bibi (Song Dynasty) Wang Anshi

The eaves are long and swept clean without moss,

The flowers and trees are planted by hand to form a border.

A river of water protects the fields and surrounds them with green.

Two mountains are lined with gates and bring in green.

4. Du Fu's "The Arrival of Guests"

There is spring water in the south and north of the house, but I can see a flock of gulls coming day by day.

The flower path has never been swept by visitors, and now the gate is opened for you.

Panxiang City has far less flavor, and the bottle and wine shops are poor and only have old fermented grains.

I am willing to drink with my neighbor and call across the fence to finish the remaining cups.
