The tea market in China is very complex. Tea and Baijiu are both high-end people in China.
Take Wuyi Rock Tea, which I am familiar with, as an example. Top quality tea leaves are basically purchased by various tea merchants when they leave the factory.
Wuyi rock tea with good quality is basically only sold in offline stores.
Also, do not purchase Wuyi Rock Tea sold by Anxi Tea Company, as their rock tea quality cannot even touch the edges of rock tea.
Drinking Chinese tea is a very long process. At first, you may be deceived, but gradually you have your own tasting ability, just like tasting red wine, in order to distinguish the quality of tea leaves.
