When does the spring harvest in Tianjin begin?

As far as solar terms are concerned, spring begins in the beginning of spring (February 2-5) and ends in the long summer (May 5-7).

Picking is to pinch the middle part of the young stem between leaves with the index finger and thumb, and pick the tea by the elasticity of the two fingers. The picking time is better from noon 12 to 3 pm, and different tea picking parts are different. Some pick a terminal bud, the first leaf next to the bud is called one leaf with one heart, some pick an extra leaf with two leaves with one heart, and some have three leaves with one heart.
