简介：——In the Ming Dynasty, when a man gave a woman a betrothal gift, he needed a comb, ruler, money box, wishful scale, mirror, scissors, and abacus. Among them, the comb is the most representative. It is said that one comb is used to comb the bottom, and two combs are used to reach the eyebrows. Three combs bring a family full of descendants and grandchildren.
