Introduction to meatballs: Meatballs are a specialty snack in Taiwan, and there are regional differences in Taiwan. Lukang's meatballs are wrapped in pieces of meat, and their shape is very similar to the word "Hui", so they can also be called Rouhui. When the meatballs are cooked, the chef will use a fork to transfer the oil on the meatballs back to the pan, hence the name.
