Why is Hubei Red Bull so cheap?

The real price of bulls is about five yuan per can. If some bulls are particularly cheap, it is necessary to consider whether they are fake and shoddy products. At the beginning, when the bull just came out, there was a fake red bull on the market. The outer packaging is the same as the real red bull, but the taste is worse. You can still drink it if you drink it carefully. But the price is very cheap.
