It is said that the inventor of steamed stuffed bun was Zhuge Liang. On the way to pacify Meng Huo's class, there was a strong wind on the river. Meng Huo wanted to sacrifice his head to heaven. Fortunately, Zhuge Liang talked about humanitarianism and replaced his head with dough wrapped in steamed meat, so he got steamed buns, but at that time they were called steamed buns.
In the history of China's diet, steamed bread refers to steamed buns for a long time, and it was not until modern times that steamed buns and steamed buns were officially separated. Today, many places still call steamed buns "meat steamed buns".
