Hydrangea is usually made of colored embroidery and is a common mascot in China. In ancient China, there was a custom in some places. When girls get married, they always set a certain day (this day is usually the fifteenth day of the first month or the fifteenth day of August) for suitors to gather under the embroidered building. The girl throws a hydrangea, and whoever gets the hydrangea can become the girl's husband. Of course, girls usually look at the right person and throw hydrangeas at him for him to find. In many places, a hydrangea is tied on the top of the bride's sedan chair, which means good luck. The history of throwing hydrangea can be traced back to more than 2000 years ago. At that time, it was an ancient musical instrument made of bronze-"Feituo", which was mostly used for fighting and hunting. With the progress of society and the improvement of material life, Feituo has gradually developed into an embroidered cloth bag, that is, an embroidered ball. People often throw at each other after meals for entertainment and communication. With the development of history, it has gradually evolved into a way for young men and women to express their love.
