The Cultural Revolution lasted for 10 years in China from 1966 until Mao's death in 1976. Most of the teas were made in the old factories and was channeled through the government and CNNP state ownership. This is a tea which is based of great old wild leaves that have aged to perfection over over 50 years. This special taste cannot be copied and the tastes have become rich and deep over time. The tea has been stored in natural Hong Kong dry storage for many years. The leaves have an almost shu taste because of the age and maybe slight old time processing which gives each tea it's unique level of sheng to begin with. This tea came in plain cardboard boxes with leaves and stems as the old wild trees are harvested. It contains flaovrs of ginseng, orchid and lotus which are special tastes for older teas. There is a great palate with this tea and it is a fine representation of a tea this age. Enjoy.
