In most places, Spring is all about the smell of blooming flowers, but in Chinese cities like Dongyang, the streets reek of urine. No, the smell doesn’t come from drunk people reliving themselves in dark corners and back alleys, but from the large pots of Virgin Eggs. Called tongzi dan (literally “boy egg) they are an old culinary tradition listed as part of the Dongyong cultural heritage, similar to tea eggs – hard boiled eggs soaked in soy sauce and vinegar. The only difference is Virgin Eggs are soaked in urine.
