I can tell you responsibly that beating beef and beef tendons are not the same thing. To put it bluntly, cow beating is a pile of drooping meat under the cow's neck and in the back of the cow's belly. There is lymphatic tissue in it, so be careful when eating it. There are toxins in the lymph. Just pick it clean and eat it. Hui hotels are all available, especially in Changchun. If you want to cook and eat it yourself, I suggest you buy Haoyue gota, which is cleaner.
