Appreciation. 10 years ago, the old chapter that cost more than 500 yuan can appreciate now. The price before 10 was only 8 yuan /kg, and after 10 years, the old chapter 1 kg is about 800 yuan. It is also recognized in the industry that Laobanzhang tea represents the highest level of Yunnan Pu 'er tea. The raw materials are good, but the output is very low, which makes Laobanzhang tea more valuable for collection and has more room for appreciation than other Pu 'er teas. In 20 18 years, the price of Laobanzhang Pu 'er tea has completely increased by 1250 times, and it has become the highest price of tea in Menghai tea area.
