What is a tea branch?

From the meaning of Putonghua, the word tea branch means: all lignified and non-lignified branches of tea trees, whether twigs or twigs; The other is directly transliterated from Minnan, Fujian. It is said that non-lignified branches, usually called tea branches, are transformed from non-lignified branches during tea processing, and the standard name is called tea stems. I guess this question asked by my friend may have the second meaning.
