There is an old Chinese saying that goes "hanging an egg on a child's chest can prevent them from contracting summer illnesses". Thus, many parents will prepare boiled eggs for their children on the Start of Summer.

Children often play "egg battle" games on the Start of Summer, where the goal is to prevent one's egg from breaking.
