On Hangzhou’s truly ancient Hefang Street, Fang Hui Chun Tang was founded in 1649 by Fang Qingyi. While most modern Chinese pharmacies have turned to machines for production, Fang Hui Chun Tang continues to make gao fang, an herbal medicine paste, entirely by hand—preserving a UNESCO Intangible Cultural Heritage of Humanity. The jelly-like tonic is consumed to boost the immune system.
