Virgin boy eggs or "tong zi dan" Chinese: 童子尿鸡蛋; pinyin: Tóngzǐ Niào Zhǔ Jīdàn[1]) are a traditional delicacy of Dongyang, China made by cooking eggs in urine collected from young boys.[2] Every year in early spring time, the urine of prepubertal school boys preferably under 10 years is collected and boiled with eggs and sold for 1.50 yuan,[3] around twice the price of a regular boiled egg.[4] In 2008, Dongyang recognized the eggs as "local intangible cultural heritage."[5]


Urine is collected from school toilets[2][6] or boys urinate directly into collection buckets set out by vendors.[5] The eggs are soaked and boiled in the urine.[2] The shells are cracked and cooked more on low heat like tea eggs. Cooking takes all day.[2][5][6]

Folk medicine[edit]

Dongyang residents believe "the eggs decrease body heat, promote better blood circulation and just generally reinvigorate the body."[2] According to a practitioner of Chinese medicine, urine crystals are like ren zhong bai. "It can treat yin deficiency, decrease internal body heat, promote blood circulation and remove blood stasis."[5]
