The concept of bulk tea comes from the concept of famous tea, because famous tea is based on bulk tea. In fact, bulk is primary tea, or tea that has not been processed in the later stage.

Here, it is easy to explain the concept of famous tea. Famous tea is finely processed tea. For example, black tea, which is bulk tea after primary processing, can be exported and processed by some enterprises.
