Xuele never thought that a volunteer would ask a volunteer teacher to write the story of her life; she also thought about meeting the Baisheng boy who was dependent on her grandma and whose life experience was a mystery; she never thought that the second half of this boy's life would be constantly intertwined with hers, like two spiraling red lines, looking for each other's direction and finally converging into a tough red rope.
Perhaps Shi Xi, who had never met Xuele, would have stayed with his elderly grandma in the mountains all his life, and Xuele, who had not met Shi Xi, would have quietly found a school in his hometown to teach and educate people. But the gears of fate changed direction, starting from that summer.
