Why can't beginning of spring get a haircut?

Beginning of spring is not suitable for a haircut, which is unlucky. As the saying goes, hair is the vegetation of the human body, which is warm in spring and grows with vegetation, and the new vegetation is damaged, which is not in line with the principle of vegetation growth in heaven and earth. There is a custom among people all over our country that dragons can only get their hair cut on February 2nd after beginning of spring. It is said that breaking this taboo will hurt his uncle.

Beginning of spring is the first of the 24 solar terms. Standing means "start"; Spring represents warmth and growth. Twenty-four solar terms were originally formulated on the basis of "variable stars". When the bucket handle of the Big Dipper points to the shade, it is beginning of spring. At present, solar terms are determined according to the longitude of the sun. When the sun reaches longitude 3 15, it will be the beginning of spring, and the festival will be held from February 3 to 5 of the Gregorian calendar every year.
