KUNMING, Oct. 7 (Xinhua) -- Pulling a cart of cement, Cai Qingkai, a former truck driver, builds his new two-story house surrounded by coffee trees, which he began to cultivate 14 years ago accidentally.
Cai used to be a truck driver in Zhaotong City, southwest China's Yunnan Province. He first encountered and immediately fell in love with coffee trees when he visited a relative in Pu'er City, Yunnan.
