A rice noodle roll, also known as a steamed rice roll and cheung fun, and as look funn or look fun in Hawaii, is a Cantonese dish originating from Guangdong Province in southern China, commonly served as either a snack, small meal or variety of dim sum. It is a thin roll made from a wide strip of shahe fen, filled with shrimp, beef, vegetables, or other ingredients. Seasoned soy sauce – sometimes with siu mei drippings – is poured over the dish upon serving. When plain and made without filling, the rice noodle is also known as jyu cheung fun, literally "pork intestine noodle", a reference to its resemblance of a pig's intestines. There is no official recording of the history of rice noodle rolls; most cookbooks claim that it was first made in the 1930s. In Guangzhou, Guangdong Province, people called the dish laai cheung because it is a noodle roll that pulled by hand.

Cantonese or Guangdong cuisine, also known as Yue cuisine, is the cuisine of Guangdong province of China, particularly the provincial capital Guangzhou, and the surrounding regions in the Pearl River Delta including Hong Kong and Macau. Strictly speaking, Cantonese cuisine is the cuisine of Guangzhou or of Cantonese speakers, but it often includes the cooking styles of all the speakers of Yue Chinese languages in Guangdong.
