In 1942, Mr Tan Tiong How came to Singapore from Fujian, China in search of a better life. He worked hard as a coolie, saved his wages and sent it back home to provide for his family. To add flavour to his meals of plain porridge, he started fermenting his own soya sauce using his grandmother's recipe. It soon became popular among his friends as it reminded them of the taste of home. In 1951, Mr Tan decided to make soya sauce from home and sell door to door from his tricycle. After years of hard work, Mr Tan started his factory and called it Nanyang Sauce Factory in gratitude for the new life he had here.
