Director Sam Wood adopted a flashback technique to explain that Chips, a Latin teacher, had taught painting at the Brookfield School in England from his youth to his entire teaching career when he retired from the school 60 years later, during which he experienced serious Muna when he was young, the happiness of marriage and the pain of losing his wife in middle age, and even the kindness and tolerance in his later years. Give full play to the great spirit of a good teacher who sticks to his post and works hard to teach from the ordinary.
