The difference between louver and hairy belly:

1. The louver is thinner and the hairy belly is thicker;

2. Venetian blinds are obtained by bleaching hairy tripe;

3. The flap stomach of cattle is commonly known as tripe, and the hairy belly is the epithelium of the second stomach of cattle;

4. There are many small protrusions on both sides of the louver, like small thorns, and the hairy belly is smooth in appearance;

5. Venetian blinds are usually eaten by rinsing (for example, scalding hot pot), and hairy tripe is usually cooked and cold, or cooked with winter bamboo shoots and lettuce.

Extended information:

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). The rumen can tear off the serosa of cattle, keep the mucosa, and rinse raw slices, such as "hairy belly hot pot" 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.
