L i Xuhui is a Chinese billionaire who built her fortune through a long career at Foshan Haitian Flavouring & Food Co., the world's largest soy sauce maker. She joined the company's predecessor in the 1990s and played a key operational role, notably managing the company's massive oyster sauce factory for over a decade (1999–2010). Her tenure coincided with Haitian's rapid modernization and expansion, which transformed it from a regional brand into a national condiment giant.

She served as a director and vice president of the company, contributing to its strategic direction before stepping down in 2016. Haitian went public on the Shanghai Stock Exchange in 2014, unlocking significant wealth for its long-time executives. Li retains a substantial equity stake in the company, which continues to dominate the Chinese market for soy sauce and oyster sauce.
