Why do ancient people throw hydrangeas to attract relatives, and the ugly ones can only be accepted silently?

Although the way of throwing hydrangea to choose a spouse did not exist in the real life of the ancients, the description of this plot still has some basis. It is said that throwing hydrangea is related to Zhuang folk customs. In Song Dynasty, the game of throwing and catching colored balls has been a way for young men and women of Zhuang nationality to express their love. Zhu Fu, a poet in the Song Dynasty, recorded in Xi Man Cong Xiao: "At the age of 18, men and women in the wild were divided into two friends, each with five-color capsules and bean millet, which was called' Feituo'." This kind of colored ball is the most common round, but also oval and diamond. It's as big as a fist, and it's full of objects. There are ribbons and red pendants at the upper and lower ends, respectively, and the ribbons are dazzling when dropped. This kind of colored ball is the embryonic form of hydrangea in the future.
