Photo taken with a drone on Sept. 9, 2020 shows the school building of Miaoben Primary School (in white) and its mountainous surroundings in Zhongcheng Township, Rongjiang County, southwest China's Guizhou Province. Gun Luquan and his wife Pan Mingzhen are a teacher couple who dedicated themselves to rural students at Miaoben Primary School for more than 20 years in mountainous Rongjiang County. As the school's only two remaining teaching staff members, Gun and Pan have never given up their original pursuit and tried their best to provide students with decent school experience.
