Also known as Lei Er, the seventeen or eighteen-year-old son of Kang Yan and his first wife. He lost his mother in childhood and was raised neglectfully by his busy father, leading to bad habits including drinking, gambling, and visiting brothels. He had not yet reached Ruo Guan age. He was kept outside during the ghost confrontation by Lü'e and Lian Xia, and later bound Chen Jinmei to report her to authorities after his father's ghost revealed the evidence.
