"Peeing Cow Pills" is a traditional Chinese food with a long history. Songjiang, an ancient town in the south of the Yangtze River, was carefully developed by the Wang family through special techniques and recipes. Later, it was transferred to Hong Kong by descendants of the Wang family and gradually became a famous food on Hong Kong Island. It has spread for nearly 2 years, swept Hong Kong, Taiwan and Southeast Asia, and dumped countless diners. During the Opium War, Hong Kong-style beef balls spread abroad, and even the Queen of England named the food "Gong Wan"

Those who have seen Stephen Chow's "The God of Food" will definitely remember the scene in which Stephen Chow played table tennis with beef balls, and the "Peeing NiuWan" in the film is fascinating.
