A young police officer from Shanghai investigating human trafficking cases on trains. He has a dark complexion and is described as handsome. He is the younger brother of Zhao Moting. He became immediately attracted to Lin Qiao'er's beauty and gentle manner after she provided him with information about traffickers. He is enthusiastic and somewhat forward in his approach. He has a childhood rivalry with Zhou Jinhui, with whom he grew up as neighbors in the Zhao and Zhou families. His mentor is also a police officer working on the same case. He is dedicated to his work, having developed blisters on his lips from anxiety over the unsolved trafficking cases involving abducted children and women on trains.
