Peeing Niuwan is called this name mainly because when making this kind of meatball, there will be some soup inside the meatball, and when eating, these soup will be sprayed out with people's chewing, which is a bit like a cow peeing, and the main material of this meatball also contains beef, so it will be called Peeing Niuwan.

Another reason is that the raw materials of Pisui Niuwan contain shrimp crawfish, which is called Pisui Shrimp in Hong Kong.

Peeing Niuwan is special. In the process of eating meatballs, soup suddenly comes out, which fills the whole mouth and activates the taste buds at once. This taste is incomparable to other foods. In Hong Kong, people eat several peeing beef balls every day, and if you travel to Hong Kong, the tour guide will definitely recommend this snack to you, because this snack can be said to be a representative food in Hong Kong.

Extended information:

Most mainlanders learned about Peeing Niuwan mainly through Stephen Chow's movie "The God of Food". In fact, Peeing Niuwan was born very early. As early as the Shunzhi period of the Qing Dynasty, peeing Niuwan had been developed, and then it was tossed and turned, introduced to Hong Kong, and carried forward in Hong Kong, becoming the most famous snack in Hong Kong.

Every time I eat a pee-cow pill, the first thing that pops out of my mind is the "Explosicum pee-cow pill", which is interpreted in a fantastic way. When I bite it down, I only hear a "snow" sound, and I'm unprepared. The rich juice just opens in my mouth in Explosicum. Is that a bit like peeing?
