Tianjin Huanghui is a unique Mazu festival in northern China, formerly known as "Niangnianghui" and "Tianhou Shenghui". According to folk legend, this festival originated in the Yuan and Ming dynasties, and its written history began in the fourth year of Kangxi in the Qing Dynasty (1665). It was later renamed "Huanghui" and has been passed down to this day. It is large in scale and has a strong local flavor of Tianjin. Every time there is an Huanghui, the people of Tianjin often come out in full force, and the scene is very impressive. Huanghui is an organized, planned, and strictly regulated temple fair. The performances include dozens of types such as street cleaning, door flags, Taishi, Jieshou, Zhongfan, Kuagu, Kangxiang, Chonglu, Shibuxian, Dharma drums, dry boats, Yangko, flower drums, hydrangeas, Baoding, Baochai, Luanjia, Jiexiang, Lanterns, Jiejia, Huagai Baosan, Dingma, Baotong, Rizhao, Lanterns, Dale, and stilts, which basically condense the essence of Tianjin folk skills. Each performance group appeared in the Imperial Assembly in the form of a "hui". Each art form had several "huis" with different styles. These "huis" ranged from 20 to 30 pieces to more than 100 pieces. The content of the performances and the number of "huis" were not exactly the same at each Imperial Assembly.
