Li Jun, 55, a police officer in Guangxi Zhuang autonomous region, has provided public security services along the Guizhou-Guangxi electric railway since 2009. The Nandan police station where Li works supervises the railway line, which runs across the mountainous areas of Guangxi Zhuang autonomous region and Guizhou province. Geographical conditions makes patrolling the area difficult. After work, Li frequently offers help to villagers living along the line, and was even gifted a horse in gratitude in March 2016. Li said the horse makes his work more convenient.[Photo/Xinhua]
