The cost of a catty of handmade dumplings stuffed with pork and cabbage is $18. If you calculate the price of $30 per catty of dumplings, the net profit per catty of dumplings is: 30-18=$12. If a dumpling restaurant's flavor is good enough, as well as the location and quality of the store, then the profit of dumplings is still relatively OK. Dumplings, also known as dumplings, are loved by the Chinese people and are a staple food and local snack in northern Chinese folklore, as well as a New Year's festival food.
