Explanation of claw hair fracture

Jane: Same as "cut". It originally refers to the ancient people who cut off their hair and broke their toes as sacrifices during divination and sacrifice, instead of using their bodies as sacrifices. Later it was used to express a very pious prayer for rain. The origin of the idiom: Book II of the Great Biography of Shangshu: "Soup is a cut claw and a broken hair. It thinks it is a sacrifice, but it prays to the mulberry society. It rains cats and dogs, and it is thousands of miles away."
