Origin of oyster sauce

Thiis sauce was invented in 1888 in Nanshui, China. A man called Lee Kum Sheung had a food stall in which he served oyster soup. One day, he left the soup simmering on the stove and got distracted. Several hours later, he realized that the soup had thickened into a viscous brown paste, rich in flavor. He tasted the sauce and began to sell it as a rice seasoning. It soon became popular and Lee set up his own company to sell his newly invented sauce. Today, the company sells different sauces and condiments, exporting them to different corners of the world.
