Chu Sanning is the protagonist, an educated youth sent to the countryside. She is resourceful, independent, and skilled at surviving in rural settings. Despite having enough food, she appears frugal, which causes jealousy from others like Zhao Jiayun. She is kind to children like Jiang Pan'an and forms a warm relationship with the Jiang family, especially Lin Xiuzhi. She is pragmatic, avoids unnecessary conflict, and is not afraid to stand up for herself. She catches sparrows and cooks well, contrasting with the chaotic dormitory life.
