Extended data:

A tripe is a tripe. Cattle are ruminants, and * * * has four stomachs. The first three stomachs are esophageal variations, namely rumen (grass belly), reticulate stomach (honeycomb stomach, hemp belly), flap stomach (double flap stomach, louver, hairy belly), and the last one is true stomach (abomasum).

The meat column on the inner wall of rumen is commonly called "belly collar, belly beam and belly kernel". The cardia dilates muscles, and the meat is thick and tough, commonly known as "belly tip" and "belly head" (soaked in alkaline water to make it crisp and tender, and can be cooked separately). Rumen can tear off the serosa of cattle, keep the mucosa, slice raw and rinse, dishes such as "beef omasum hotpot" and "husband and wife lung slices". The application of reticulum is the same as rumen. Flap stomach and abomasum are mostly used for shredding. Belly collar and louver are widely used in tripe.
