Sumo (すもぅぅぅぅ): A sport similar to wrestling, which was called Jiao Jiao in the Qin and Han Dynasties and sumo in the Southern and Northern Dynasties to the Southern Song Dynasty. It was introduced to Japan around the Tang Dynasty, and now it is a popular wrestling sport in Japan.

China and Japanese have sumo in history. Judging from some unearthed cultural relics, the image of China Jiaodi in Qin and Han Dynasties is very similar to the popular Japanese sumo. In modern times, sumo has always been regarded as a Japanese martial art. In fact, there was a similar "wrestling" in ancient China. As early as the early Western Han Dynasty, there was a popular folk game in Jizhou (now Hebei): people wore masks with horns, competing and fighting with each other. This kind of activity, which is both a competition and a performance, is called "Jiao Di", also known as "Chiyou Opera".
