Walking on snow
In Chinese, Pinyin is B ù Xu ě L ǚ Chu ā n, which means to be poor. From the preface of sending Zheng Wu to the new capital.
The idiom comes from Wang Wei's preface to sending Zheng Wu to the new capital of the Tang Dynasty: "it's poor but not ill if you can see it with your elbow in your hand and walk in snow and wear it with your feet."
