Also known by his nickname Lu Jianjian, he is the youngest child of the Lu family and Lu Jianyan's younger brother. Described as the little crown prince representing the Wu County Lu branch. He is mischievous, rebellious, and somewhat unruly — he once took a break from school for deliberately hitting a classmate. He recently returned to school but continues to cause trouble, such as failing baseline tests, forging his mother's signature, and forgetting about parent-teacher meetings. He is the eternal source of amusement for his older siblings.
