„guan mu; 灌木 - Literally means bush or shrub. 灌 - guan, to irrigate. This style of cultivation is relatively new in Yunnan, having only started in the early to mid 20th Century. Tea bushes are cultivated in rows. Guan mu cha is the tea from cultivated bushes.“

„Yunnan Tea Company standardized the trade number for Pu Erh Tea in 1976 for the purpose of export. Each bingcha has 4 digits: the first 2 digits indicate the manufacturing year, the third digit indicates the leaf grade, the last digit indicates the tea factory (e.g. Kun-Ming 1, Meng-Hai 2, Xia-Guan 3, Pu Erh 4). The loose-leaf tea has 5 digits with the third and fourth indicating the class level of raw materials. Examples of early trade numbers for Puerh Tea are 7452, 7562, 7572, 75671, 76563.“

„There is also a lack of formal definition for "gu shu." Some say "gu shu" should only refer to trees over 300 years of age, that is left to grow tall, and not pruned back. But in reality, most "gu shu" trees are cultivated, which entails annual pruning to encourage regrowth & lower branches for easy picking. A lot of "gu shu" on the market comes from trees as young as 100 years old, some of which is as short as 1.5m high. But a 100 year old tea tree growing in the wild can also grow higher than 3m high. Eventually the government will legislate what classifies as "gu shu." Until then, let the buyer beware!“
