Salted duck eggs, typically salted in brine, is a small dish on Chinese dining table. Gaoyou, a city in East China's Jiangsu province, is well known for the production of salted duck eggs, especially the double-yolk duck eggs, which are commonly thought to be more nutritious and are usually more expensive.
Raising ducks, processing and selling duck eggs have become a way to increase farmers' income and help them get rich. Last year, the city raised 10.35 million ducks, processed 950 million duck eggs and registered an economic output of 5.11 billion yuan ($813.48 million) in the duck sector. The products sold well in China, as well as Japan, South Korea and Malaysia.
