Fried dumpling was introduced to Taiwan Province from Japan, and the Japanese called it "Xianbei". During the Japanese occupation, Japanese people came to Taiwan Province in large numbers and brought this technology to Taiwan Province. Therefore, fried dumplings were imported from Japan, belonging to Japanese cookies and snacks, and were deeply loved by Japanese and Taiwan Province people at that time.

Xianbei refers to the puffed bread in puffed food, and it can even be exaggerated to say that it is very similar to shellfish. Every time I eat Wangwangxianbei, I will eat at least two packs. I have never been satisfied with one pack, and the more I eat, the more addicted I am. For this kind of doubt, some friends think that there must be some addictive essence added to the scallop, but the scallop has not been seized by the Food Bureau for so many years, so this rumor has been overturned. However, Xiaoyou later discovered that in fact, this Wangwangxianbei can't stop eating, not adding anything, but designing a small detail to make people more delicious. In fact, the amount of seasoning powder on both sides of Wangwang Xianbei is uneven, which is not the carelessness of the manufacturer, but is specially designed like this. Because the tastes of the two sides of the shell are different, it avoids the boredom caused by the superposition of tastes, and the different tastes can also promote appetite. It's like taking a light bite and taking a heavy bite, you will feel more delicious. Therefore, when people eat mussels, they will eat more and more delicious. After some netizens learned the truth, they called it "Wangwang".
