The first three volunteer teachers lasted two months at most. He was the fourth. He endured the tenfold pain of bone cancer. On rainy nights, he carried feverish children down the mountain, every step like walking on broken glass. On weekends, he crossed the mountains to haul bricks at a construction site. He spent all 150 yuan on exercise books and powdered milk, and ate a steamed bun himself. Half a bottle of the cheapest ibuprofen sat in his drawer. There were always streaks of blood hidden in his cuffs. The children asked him, "Teacher, are you sick?" He smiled and said, "I'm just not very strong. I'll be fine if I tough it out." A couple of vloggers went into the mountains to film, and 8,000 viewers in the livestream chat all realized something was wrong. "Why doesn't he teach standing up?" "Why are his hands shaking?" "What is that bruise on his lower back?" Nine-year-old Xiaofang blurted out on the livestream, "Teacher takes medicine every night. He told us not to tell anyone..."

He didn't know that he had long since stopped caring about the numbers.
