The official Chinese designation for this vehicle is the Type 63 but within the Chinese Army it is referred to as the Type 531. The Australian Army has reported that the Type YW 531 has excellent cross country mobility.

The Type YW 531 has an all-welded hull and is fully amphibious, being propelled through the water by its tracks. The driver and commander sit at the front of the vehicle with the driver on the left and the commander on the right. The loader sits behind the driver and the gunner's position is to the rear of the vehicle in the roof. The engine compartment is behind the commander.
