Zang Liujiang's second brother, a sickly and frail person with poor health. He is cold on the outside but gentle on the inside, as described by Zang Liujiang. He lives alone with an adopted child named Li Ao. When he was twenty, he was quite handsome and had many matchmakers, but he knew his health was poor and feared his wife would become a widow. So he adopted Li Ao and claimed to have an heir to deter potential brides. He is shown to be responsible and caring, worrying about Yu Huishui's impression and trying to maintain propriety. He gets sick easily, shivering from the cold, and needs to wrap himself in blankets.
