Chomdrang Drolma invited her friend to invest in Renkang Ancient Street in Litang County, Ganzi Tibetan Autonomous Prefecture of southwest China's Sichuan Province several years ago. That helped the local people to participate in the service industry or even start their own business. The local people had relied on cordyceps and grazing in the past, but have now gained a stable and continuous income, and changed their mindset about making a living.
