Yang Shanzhou, the former secretary of Baoshan District Party Committee, gave up the opportunity to enjoy his old age in the provincial capital after retirement, took root in Liangshan Mountain, planted trees voluntarily, led everyone to plant trees, built a forest farm with an area of 56,000 mu and a value of 300 million yuan, and donated the forest farm to the country for free.

1988, Yang Shanzhou did not go to Kunming to enjoy his old age after retirement, but rolled up his bedding and plunged into the dusty Liangshan.

Yang Shanzhou has deep feelings for the masses. In 2002, Yang Shanzhou wrote in his notebook that "* * * people are not afraid of any difficulties, but are afraid of being divorced from the masses and losing themselves." At that time, it was the fourteenth year after his retirement, but it was the old man's consciousness to keep alert and maintain the relationship between the party and the masses at all times.
