The Mengyang Guoyan tea factory is based in Jinghong but takes most of its raw material from Xi Shuang Banna and more specifically from Menghai area. The director of the factory Ms. Dong is steeped in Pu-erh tea history. She is a Dali native but after graduating from the Yunnan Agricultural University went to work at the Menghai Tea factory as a master tea blender. She worked there for more than 8 years before starting the Mengyang Guoyan tea factory back in 2003. Ms. Dong's aim is to produce a variety of medium to very high quality pu-erhs for drinking and works hard to control the quality and distribution of Guoyan products.
