It's a dish from Leshan Suqi, Sichuan! The source is: it turns out that people who can afford to eat beef are some noble people! Those who ate the beef, the other things on the cow to those working below to carry the bag ah people to eat! Those people were more generous! They put their feet up on the table and ate the beef! Eventually it evolved into today's Beef with Feet Crossed! Anyway, it's all from the cow! There are many kinds! You can go to eat to see!
