(Chinadaily) - Wang Lijiao, a 61-year old wine maker, lives in a three hundred-year-old mansion at the center of Xiansai village near Qionghai city, Hainan province. Stepping into this old mansion, one can smell the mellow scent of Wang's home-made ricewine. Wang has been carrying on his ancestral techniques of rice wine-making for 30 years since the reform and opening-up of the country. He keeps from drinking his produce, but can make superb rice wine by estimating the concentration of the distilled liquorwith his eyes.
