余仁生 Eu Yan Sang

Eu Yan Sang was founded by Eu Kwong Pui, a native of Foshan, Canton. He left his hometown for Malaya to earn a living when he was young and opened a Chinese medicine and grocery store called Yan Sang. After his death in 1891, his business was inherited by his only son, Eu Tong Sen, who expanded the business and opened a branch in Hong Kong in 1909. In the 1920s, the company officially changed its name to Eu Yan Sang and became the largest Chinese medicine company in Southeast Asia.

Hong Kong Chinese Merchants Collection keeps the business materials of Eu Yan Sang including 1,680 volumes of bound account books, auditor’s reports, remittance books, bank statements, Chinese medicine trade records, tax assessments and tax bills, and a large quantity of business letters, covering a period from 1915 till 1969.
