How to avoid hunchback water?

Bow back is a Chinese word, pronounced as G not ng bè i, which refers to the curved side of a bow.

Tang Linghu Chu's Young Travels (III): "Bow back, shine the sword and shine the frost, and the autumn wind leaves Xianyang." The Biography of Zhangzhuang in the History of Song Dynasty: "Hubei went to Guangxi, entered Hunan in twists and turns, and went from Quyang, still bowing strings." The back of the bow refers to the side where the bow and arrow bend into a radian, and the hunchback refers to the deformation of the spine, which is easy to happen in the elderly, and people who sit incorrectly all the year round may also hunchback.
