Originated in Huangyan, recorded in local chronicles to commemorate Qi Jiguang. According to legend, the origin of cake containers is related to Qi Jiguang. It is said that Taizhou people cooked a lot of dishes to reward Qi Jiajun, but it was too far away to carry and even send bowls, so smart people brought pancakes, wrapped them up and served them conveniently. So the Dragon Boat Festival in Taizhou, besides commemorating Qu Yuan, can also commemorate Qi Jiguang by the way.
