These three are Cao Teng, Cao Yu and Cao Xian. Everyone knows the first two, the latter is Cao Cao's daughter. To be honest, I am also very surprised that Cao Xian hid here, knowing that Cao Cao married her and Cao Hua Caojie's three daughters to Han Xiandi. Although she is not a queen, but according to ancient rules should also be buried with Han Xian emperor!
