The meaning of the word quoted in the ancient poem Liu Xin is expressed in one sentence.

Liu Xin

Yang Wanli in Southern Song Dynasty

Wicker brushed a hundred feet of silver pond. It was dark green with only light yellow.

Wicker can not be dipped in water, but the willow shadow in the water guides him to grow.

The word "Yin" in "Willow Shadows in the Water Lead him to Grow" takes care of the word "hundred feet" and depicts a picture of wicker connected with the reflection in the water, which is beautiful and full of movement. The word "Yin" is very kind, bringing the willow shadow (that is, the new willow) and the whole picture to life.
