Volunteer recalls long, lonely fight to protect forest

Volunteer Liu Zhenmao has protected a mountain forest in Hunan province for 38 years, spending 22 Chinese New Year's Eves at his sentry post and even missing his youngest son's wedding due to his dedication.

Liu, 71, patrols Chenzhou city's Shizikou Mountain by foot, walking more than 30 kilometers every day, and over the years has covered the equivalent of more than 10 circumnavigations of the globe.
