Yan Zhilang, also called Zhi Lang, is the son of Chi Wei and Yan Jingheng. He is described as exceptionally sensible since childhood, often acting like a small adult and even comforting his mother. He suffered a mild concussion after falling and hitting his forehead on a table corner. He does not like playing with Qiao Shiyue because she cries too much, but he has been told by his father to be good to Aunt Feifei. He eagerly awaits a puppy promised by his mother for getting first place in kindergarten arithmetic.
