What makes me feel coldest is not the cold weather but the coldness of my heart. Every time I read Mr. Chen Yinke: I have been so angry all my life that no one in the world is looking at the sunset. Thinking of his experience makes me feel cold around me.
Another example is the song of Everlasting Sorrow: the mandarin duck tiles are frosty and heavy, and the emerald quilt is cold. Years have passed since the separation of life and death, and the soul has never come to sleep. The weather is cold and the heart is cold, which is much higher than a simple low temperature state.
Tang Dynasty · Du Xunhe Snow
The wind stirs the sky and chills the bones, and the light shines through the window at dawn. There are no birds in the rivers and lakes, and the sound of breaking bamboo can be heard in the rock valley. There are many similarities between the nests, and Lu Qi has both. Don't talk coldly, Mr. Yongpao. There is a woodcutter walking barefoot among you.

Another example is this song of snow. At first glance, the environment is very cold, but actually the heart is even colder.
