Pu'er tea flourished in the ancients two thousand years ago and flourished in the royal family of the Qing Dynasty. In 1729 (Yongzheng seven years), the Qing government officially established Pu'er Prefecture, and set up a tribute tea factory in Pu'er County. Pu'er tea was officially listed in the "Tribute for emperor" in 1732, and it has been famous since then.In the ancient border trade, in order to reduce disputes in weights and measures, and facilitate statistics, taxation and trading, the government has established a mandatory standardization measure for Pu'er tea cakes, weighing 2.5 kg of 7 tea cakes in 1 tong(cylinder).
After the end of the Qing Dynasty and the Republic of China, Pu'er round tea was sold overseas with overseas Chinese. The history of overseas tea sales began. The weight measurement method of tea cakes also deviated from the traditional Chinese "liang (a unit of weight, 1 liang = 50 grams)" and changed to the international common "gram".
At that time, “China Tea” (China Native Produce and Animal Products Import and Export Corporation) had the right to export tea in China. In order to cooperate with the export, China Tea Company required the subordinate tea factory to produce 30kg of Pu'er tea per package.
According to the international unit of measurement, one is a dozen, that is, 12 cylinders. The habit of each cylinder according to the Qing Dynasty is 7 cakes, so the weight of each cake is 30kg÷12 cylinders÷7 cakes ≈ 357g. This is the derivation of 357g per cake of Pu'er tea.
2 Interpretation from the perspective of “I Ching”
The yin is the Moon (the number is 2, 4, 6, 8, 10), which is water and condensate. The sum of the yin numbers is 30, which is also the mystery of 30 days per month.
Take 3, 5, and 7 for Mid-Yang, which is a lucky number.
