Chengde people tell you that Lulu is the brand of Almond Dew, just like Coke has Coca-Cola and Pepsi. Lulu is of good quality and high popularity. Colleagues have some small shops that make other brands of almond dew, and the packaging and trademarks, as well as the names, will be very confusing, such as "Chengde almond dew" you said. Look at the trademark when you buy it.

By the way, Lulu, a tin can, is a native of Chengde, and Lulu, a carton, is made by a branch factory in Guangdong, but I don't think it tastes good.
