Northeast tea seeds and stupid tea seeds refer to the same kind of food, that is, granular food processed from corn. Among them, "Dachazi" is a northeast dialect, and "Benchazi" is a common name for this kind of food in other regions.

In addition, according to the different processing methods and raw materials, this kind of food can be divided into sticky slag and ordinary slag. Among them, glutinous rice residue is made of sticky corn (also known as "waxy corn") through soaking, grinding, filtering, cooking, cooling and other processes, with sticky taste and usually white or yellow color. Ordinary ballast is made of ordinary corn, with loose taste and yellow color.

Therefore, the difference between northeast barbecued pork bun and stupid barbecued pork bun lies in the different names and regions, and the difference between sticky and ordinary pork bun lies in the different raw materials and manufacturing technology, which leads to different tastes and colors.
