Is the inner integrity and inner flying of Pu 'er tea the same thing? When did the inner ticket first appear?

Not the same thing. The inner fly (correct spelling: inner leaf) is pressed in the tea cake, and the inner ticket is wrapped on the outer cotton paper independently of the tea cake. The use of internal flight is usually to identify the manufacturer (it is not easy to imitate when pressed in tea), and the internal ticket usually tells the characteristics of Pu 'er tea (such as the 7542 internal ticket) or the degree of tea.

For example, "50 1" represents the first batch produced in 2005.

The inner beauty and inner beauty of Pu 'er tea are Pu 'er tea products made by tea factories in order to promote tea products and increase commodity circulation. They are the predecessors of today's Qizi Pu 'er tea cakes and are the "ancestors of modern Pu 'er tea seed products".

Extended data

Pu 'er tea has a very long history. As early as 3,000 years ago, during the tea-picking period of King Wu, the ancestors of Yunnan who planted tea had already offered tea to Zhou Wuwang, but there was no name of Pu 'er tea at that time. The transitional ancient tea tree outside the state is a living fossil left by the ancient Pu people who cultivated and domesticated tea trees.

Tang dynasty. In historical documents, it is recorded that the earliest person who planted Pu 'er tea was Fan Chuo, an official of the Tang Dynasty. "Schumann" Volume 7 says, "Tea comes from Yinsheng City, and there is no way to pick it." Meng Sherman drinks it with Chili, ginger, cinnamon and stir-fry. "

According to textual research, Cheng Yinsheng's tea should be Yunnan Daye tea, namely Pu 'er tea. According to historical records, as early as 1 100 years ago, tea was abundant in Sipu District of Nanzhao, which is surrounded by mountains in Yinsheng City.
