Tea tree is an evergreen small tree which cultivated mostly in subtropical regions. Its root grows vertically down for six feet in depth and it tolerates difficult temperatures.

	Depending on harvesting period, it can be grouped into Spring-tea, Summer-tea, and Autumn-tea or first-harvest, second-harvest or third-harvest. A bud that harvested before 20th of April usually classified as high-quality.   The type can be sorted as tea-leaves and tea-powder. In ancient times, tea-leaves was made into lumps or chunks for the preservation purpose and broken down into powder form as needed.
