Pig fallopian tubes (Chinese: 生肠; pinyin: shēng cháng; Cantonese: sang cheong) is a traditional, Malaysian stir-fry dish.

The dish is prepared by stir-frying fallopian tubes (sometimes the uterus)^[1] of pigs and serving chopped with vegetables and sauce such as kung pao sauce^[2] or soy sauce with ginger and onions;^[3] the meat is relatively flavorless but is a good vehicle for sauce. Other protein sources such as dried shrimp may be added.^[4] The texture of the meat has been described as combining crunch with springiness.^[1][2]

Although traditional, the dish is not often served in Singapore.^[4]

Consumption of pig fallopian tubes supposedly has a beneficial effect on a woman's fertility.^[4] It has been categorized by Catherine Ling of CNN as one of the "10 grossest foods in Singapore".^[2]

The dish is sometimes imprecisely referred to as pig intestine.^[5] One Singapore restaurant was serving it in 2015 as "Famous Pig's Intestines".^[3]
