Jiudou Bowl, also known as Dam Banquet, Running Water Mat, Nine Bowls, Nine Bowls, etc., is one of the traditional dishes in Sichuan, which focuses on steamed vegetables, originally named after the nine dishes of steamed vegetables. They are: soft fried steamed pork, steamed ribs, steamed beef with flour, steamed soft-shelled turtle, steamed muddy chicken, steamed muddy duck, steamed elbow, meat with sand and salted boiled white.

At the same time, in Sichuan dialect, "dou" means a big container, and using nine bowls to call this scene also means praising the abundance of its dishes.

The structure of the "nine bowls" of Sichuan folk banquet guests is generally as follows: steamed head bowls (generally, there are steamed head bowls, crispy meatball head bowls and miscellaneous shaking head bowls), meat buckles (boiled white) and miscellaneous buckles (steamed meat with powder) are the main dishes; In addition, it is served with pig's tripe and leftover materials of the above four dishes, and mixed with bamboo shoots, taro, simmered or kelp and vermicelli to make five bowls, that is, nine bowls. If it's all pork and mutton (beef didn't serve in the old days) and there is no chicken or duck, it's also called "big water mat". The poor farmers often subtract the braised pork from the last meal and mainly go into the water with their heads and feet (miscellaneous belly), which is also called "eight bowls of water" Rich people, in order to show their wealth, often add main ingredients to the first bowl, which are called "tendon mat", "bamboo sun mat", "sea cucumber mat" and "shark fin mat" respectively to show their higher grades. Some also make a fuss about the last dish, adding steamed chicken, pork ribs and seaweed with mushrooms as "mushroom seats", burning sand hot pot as "hot pot seats", and the top-grade chefs from Zhaotong and other places are invited to hold "barbecue seats". In the 1990s, the "nine bowls" not only changed their packaging, but also spread from pork to chicken, duck, fish and seaweed. At the same time, the number of dishes also increased from nine to several times that of nine. The old "Nine Bowls" only remain in some rural areas.
