1, look at the freshness of tea: it doesn't mean that the longer tea is collected, the more mellow it will taste. If the tea leaves are covered with dust or even moldy, be careful.

2, look at the color of tea: some tea itself is very bad, and some merchants will deliberately color it in order to sell it. Therefore, before buying tea, we should make a cup to see the color of tea.

3. See if the tea is wet: Generally, the tea sold is dried. When buying tea, if it is found to be wet, it is generally of quality problems and cannot be purchased.

4. Find a regular merchant: If you like to drink tea and drink more every day, we must find a regular merchant to buy it. Generally, the quality of tea there is good, and the tea is also very good.
