This item was purchased at the Daimaru department store in Hong Kong about 40 years ago. It has been stored in a dry place under the floor. I am looking for someone to use it. This is a Yunnan Province Chi Tse Beeng Cha (a round tea cake of Pu-erh tea). It is labeled "Yunnan Chi Tse Beeng Cha". The name of a traditional tea cake made by solidifying Pu-erh tea into a disc shape. The "tea" mark in the center → A representative design of Yunnan tea. "China National Native Produce & Animal By-Products Import & Export Corporation" A notation of a state-owned company that once handled China's exports. Often seen on old Pu-erh tea. The weight is indicated as 320g. When measured with a scale, the weight including the wrapping paper is approximately 357g. What kind of tea is this? Pu-erh tea is a post-fermented tea made in Yunnan Province, China. The flavor deepens by solidifying it into a cake shape and aging it. From the packaging and logo, it appears to be a Pu-erh tea cake from a relatively old era (possibly vintage). The photo shows Yunnan Province Pu-erh tea ("Yunnan Chi Tse Beeng Cha"), but it is not possible to determine the exact year of manufacture from the photo alone. However, it is possible to estimate the "approximate period" from some of the features. Features that can be read from the photo Label of China National Native Produce & Animal By-Products Import & Export Corporation, Yunnan Tea Company (= "CNNP (China Tea)") Weight is indicated as 320g The outer packaging is an old type of printing A small price sticker (probably from the import store) Points of inference Traditional "Chi Tse Beeng Cha" usually has a standard weight of 357g, but this photo indicates 320g, so This is likely for export to Hong Kong or a specific era's export standard. 320g cakes are a relatively common standard for Pu-erh tea exported in the 1980s and 1990s. Conclusion (estimation) It is highly likely that it was manufactured around the late 1980s to the 1990s.
