A tall, lean boy around thirteen or fourteen years old, known as Brother Lidong. He is the famous childhood sweetheart of Xia Qiumeng and accompanies her everywhere like a knight. He started junior high at the affiliated middle school of the teacher's college. He wears a loose blue-and-white school uniform with a military-green satchel. He is playful and funny, pulling ridiculous faces to make the children laugh during the photo.
