Introduction to the Embroidery Building: The Embroidery Building is the venue for the large-scale interactive performance "Tossing the Hydrangea Ball to Recruit a Son-in-law". The performance is adapted from the traditional flower drum drama "Touching the Sedan Chair" and interprets a story that happened along the Huaihe River. : The daughter of Zhang Yuan's wife was about to get married. The emperor remembered that the Zhang family was the home of the world's richest people, so he specially ordered an hydrangea ball and ordered the local county magistrate to throw hydrangea balls for Miss Zhang to attract the bride. While watching the performance, tourists can also participate in grabbing hydrangeas and eating wedding candies, which is a truly enjoyable experience.
