Tea culture is an important part of traditional Chinese culture. With social development and progress, tea not only plays an important role in pushing the development of the economy (经济的发展), but also becomes a necessity in people’s lives. If you are a tea lover, there are four basic steps you should take in choosing suitable tea.

1. Watch. Good or fresh tea is bright green in color and in a close shape, but poor tea is loose and dull. The leaves should also be dry.

2. Smell. Good tea, especially fresh tea, has a pleasant smell while poor tea smells sour.

3. Taste. You can taste the leaves by chewing them carefully. Good tea leaves have a fresh mellowness (醇香) with a little bitterness and a lasting sweet after taste. Bad tea doesn’t taste good and has a dark color.

4. See the infused (冲泡过的) tea leaves. If the tea is good, the infused tea leaves should be even without impurities (杂质).

After you buy good tea, keep it in a dry, cool place and avoid direct sunlight. It’s best to put it in a dry can.
