There is a canteen in Yunbian | Life is hard, but it is sweet with you. Liu Shisan grew up in the small town of Yunbian. His grandmother Wang Yingying and the girl Cheng Shuang were the light of his life. Grandma's love is simple and deep, and Cheng Shuang's company is as distant as ever. Liu Shisan stumbled along the way, from a young boy to experiencing the vicissitudes of life. Stories about dreams, love, and family affection were staged in small towns. The world described by Zhang Jiajia is full of fireworks and joys and sorrows of ordinary people. There are laughter and tears, reunions and partings in the book. The words flow through the heart like warm water, asking people to find themselves in other people's stories and taste the true meaning of life. One book, one world, "cloud edge" is waiting for you to explore and encounter the softness in your heart.
