A chessman has a main body (1) provided with at least one air duct (2, 3, 4). The air ducts are formed by passing through the main body (1). The air ducts, which are mutually perpendicular, pass through the center point of the main body and are arranged in the main body. The air ducts allow the airflow to pass through the air ducts in the main body (1) to reach the other end of the main body from any angles, so as to delay the dangerous situation of suffocation caused by swallowing the chessman and gain the necessary time for rescue. |
