Chezai noodles are a kind of low-priced special noodles in Hong Kong. Chezai noodles appeared in the 1950 s, when the living standards of Hong Kong people were low. Domestic refugees flooded into Hong Kong, making it difficult to make a living. Mobile vendors have mushroomed on the streets of Hong Kong. At most, it is to set up a car stall and sell cooked food such as curry, fish eggs and car noodles.
