Origin

According to a Chinese legend, an emperor traveling in disguise found out that his citizens were suffering from hunger. Thus, he commanded butchers to kill the cows and cooked them for the starved citizens. The king hoped every citizen could eat it. So besides of cooking the beef, entrails of cows were also put into the pot to cook more. Citizens thought the dish tasted good and the dish has passed on from generation to generation.

In Hong Kong

Ngau zap had been a popular kind of snacks in Guangdong province of China. Due to the Chinese Civil War of the mid-20th century, a wave of migrants from mainland China flooded into Hong Kong as refugees. With the influence of the migrants from Guangzhou, Ngau zap became popular in Hong Kong. With the economic boost of Hong Kong in the 1970s, the fusion of Chinese and Western cultures led to the popularity of Ngau zap among foreign visitors. It is common to buy Ngau zap from street vendors, which is another unique feature that can be found in Hong Kong. Under the law, if the street vendors fail to get licenses given out by the Food and Environmental Hygiene Department, they cannot continue their business as they may cause hygienic problems, and hawkers may worsen the city image of Hong Kong. In 1958, the government set up Hawkers Control Teams to combat street vendors. However, starting from the 1970s, the government has slowly stopped giving out licenses to street vendors. It resulted in the disappearance of many street vendors, thus the places selling Ngau zap.

On the bright side, the standardisations of operations and the maturity of market help further the development of Ngau zap in Hong Kong. Beef entrails have become one of the must-eats in cart noodle shops and cha chaan tengs. Some people have stopped vending on the streets and opened beef entrails restaurants.
