Daketang (Dak Town), a Shanghai tea house in Xuhui (French Concession) specialising in Pu'er tea from southern Yunnan, housed in a 1933 French-style mansion. The Chinese characters are from a famous saying 'Go Drink Tea!', which is the answer the Chinese Zen MAster Zhaozhou gave when once asked by a monk 'What is Buddha?'..Blog.Housed in a 1933 French mansion, Daketang is a tea house on a grand scale. This is Shanghai, in Xuhui district, better known to Westerners as the former French Concession. And if you want to know how highly tea can be valued in China, this is a good place to visit, because Daketang specialises in Pu’er tea. This variety, as I learned shooting the Tea Horse Road, has a particular quality, which is that it ages slowly and gracefully in a natural fermentation. Old cakes of Pu’er – decades old, that is – are worth a fortune, and you can find some very old ones here.
