Hui Lau Shan founded his first herbal drink store in Yuen Long, Hong Kong, in the 1960s. Despite the initial success with his Guilinggao and herbal drinks, Hui Lau Shan did not settle and continued to innovate. In 1992, the creation of Hui Lau Shan’s unique and unparalleled “Mango Sago” dessert won the hearts of the island.
