Male, Lan Tingzhou's younger brother by six years. When the Lan family moved to Qingshui Town he was only five years old. Due to malnutrition he was frail and sickly as a child, like a little kitten. As outsiders in Qingshui Town he was often bullied by local children. Gan Cai'er stood up for him and forced bullies to apologize. He picked up the bad habit of being quick to resort to violence, had no interest in studying, and spent his days playing with swords and sticks. With Gan Cai'er backing him up he nearly became the local bully of Qingshui Town. Lan Tingzhou sent him to Xuancang Mountain to train in martial arts. He has a loose tongue and wrote about family matters for outsiders to know.
