Where can I buy bulk beef sauce in Linping?

I don't know what kind of meat sauce you are talking about. As far as I know, general supermarkets don't sell meat sauce, and only a few large supermarkets sell some beef sauce.

If you want to eat and you can't buy it, you can make it yourself. Buy 2 taels of pork belly, 300g of soy sauce, a little chopped green onion and Jiang Mo, 80g of water, and appropriate amount of chicken essence, monosodium glutamate, sugar, soy sauce and thirteen spices. Practice; Cut pork belly into pieces, heat the pot with high fire, add 30g peanut oil, stir-fry pork belly in the pot, add minced onion and ginger, stir-fry for a while, add water and the above seasonings, and then boil for a while. The sauce will become more fragrant, so it's best to sprinkle some chives before cooking. It's that simple. Eat and cook!
