Rong Jiasheng, the founder of the Mengkurong clan, was born in a tea-making family and completed the leap from a tea-making workshop to the tea industry. In 1999, he acquired the bankrupt Shuangjiang County Tea Factory and established Yunnan Shuangjiang Mengku Tea Co., Ltd. Shuangjiang Tea Factory is specially used to make Pu'er raw tea, in 2006, Shuangjiang Mengku and the new Yongde Tea Factory is mainly used to make Pu'er ripe tea, is the only raw and cooked system in the industry of two professional differentiated plants, the total area of the two tea factories is 15,000 square meters, covering 54,000 acres of tea can be picked, 10,800 acres of organic tea gardens, and the annual production capacity of tea is 10,000 tons. Mengkurong has been recognized as a national key agricultural leading enterprise and has obtained the certification of the only FAO organic tea demonstration base for Pu'er tea.
 
Icelandic Pu'er is now the star of Pu'er Ancient Tree Tea, which was first launched by Rong Jiasheng. In 2005, Rong Jiasheng made Pu'er tea "mother tree tea" raw cake with the fresh leaves of Mengku large-leaf tea in Mengku Iceland tea area as raw materials, with fine materials, picking one and two tea cyanine as raw materials, the aroma is pure and high lasting, the soup color is crystal yellow and bright, the taste is mellow and fresh, and the sweetness is lasting, because of its excellent quality, it is popular in the market. Relying on Rong's Iceland No. 1 base, in addition to the "mother tree tea", Mengkurong has also produced "Winning Iceland", "Iceland Jade Leaf" and other ancient tree tea cakes in recent years, in addition to the Icelandic tea area, other ancient tree teas in the Mengku area such as "Arbor King", "Snow Mountain", are also excellent cake tea that has been launched in recent years, "Arbor King" selected several tea mountains in Mengku tea area on the hundred-year-old arbor tea fresh leaves as raw materials, and the production price in 2016 was 270 yuan. "Mengku Chunjian" is a relatively conventional raw cake, also from the Mengku tea area, the production price in 2017 is 128 yuan, more suitable for new tea friends, of course, the aged raw cake drinking experience is better, the production price in 2008 is 360 yuan.
 
Most of the so-called ancient tree pure teas that are fanatically pursued in the Pu'er tea market are concepts and gimmicks, and they do not necessarily point to an excellent drinking experience. In fact, the earliest "mother tree tea" launched by Mengkurong is only made of Icelandic ancient tree tea as the main ingredient and blended with other tea mountain raw materials. In recent years, Mengkurong's main "Bojun" and "Shi Nian" series are known for their self-blended flavors, trying to promote the taste of their brand rather than the taste of the tea area. "Bojun ripe tea" is known for a variety of compound aromas and smooth tea soup and strong taste, "Shi Nian" is made of ten years of aging raw materials, the soup is mellow and amber, the price of cake and tea is more than 1000 yuan, but the "Shi Nian" series has also launched a small canned series, a single can of 30 grams is priced at 40 yuan, and there is a gift box of "golden flavor", "Enchantress Blue" to buy.
