Intern Lin Jiyu walked into the deep mountains of the north, where there are old school buildings, rough dialects, and pairs of longing eyes. She thought she was just a passer-by, but she met Principal Su who guarded an elementary school all his life, Xi'er who was as light as cotton, and a pair of boys and girls embracing each other on the edge of life and death. This is a story about "companionship" - some people will eventually leave, but before they leave, they have illuminated your life. What Dashan taught her was not how to say goodbye, but - some encounters will never be forgotten in her lifetime.
Purpose: Not all encounters are for long-term companionship. Some people stay in life for a short time, but leave a mark that can warm a lifetime.
