Lu Qingchuan saw the "Ladder to Heaven" in Duanyun Mountain - an 800-meter-high wooden plank on the cliff. Twelve children were climbing to go to school. This master of education dismantled the theory and built a mobile classroom out of scrapped buses: solar panels on the roof provide power and satellite antennas are connected to the Internet. On sunny days, he goes up to the mountains to measure cloud heights, and on rainy days he reads "The Classic of Mountains and Seas" in a shaking carriage.
Deaf student Yang Zong can touch the vibrations of his vocal cords and "see" the shape of sounds. Lu Qingchuan invented the tactile teaching method: the roughness of the sandpaper represents the tone, and the temperature of the water flow corresponds to the tone. When Yang Zong spoke his first Mandarin sentence in the speech contest, the judges' table was silent for seven seconds.
Three mobile classrooms connect scattered villages, and satellite signals allow children to see the sea. But during the unified examination, the subways, supermarkets, and elevators on the test paper were completely unfamiliar worlds to them. Lu Qingchuan established the "Mountain Life Ability Certification": rock climbing, medicine gathering, sky observation, and direction identification became graduation certificates.
When the Harvard admission letter arrived, Lu Qingchuan was debugging a new tactile sound device—Yangzong had just been admitted to the Provincial Institute of Language and Literature with exception. Principal Chen's 40-year teaching plan has been digitized, and the retired parts of the first classroom car have been turned into the first weather station in the mountainous area.
Tashi's horse team transformed into an "educational camel team" to transport microscopes and picture books in backpacks. The meaning of education is clear at this moment: it is not to let everyone go to the same exit, but to let every life see his own light in his own world. At an altitude of 3,200 meters, this light is sometimes the reflection of solar panels, and sometimes it is the brightness in Yangzong's eyes when he touches the world.
