In ancient times, this way of wearing half clothes and half armour was called "brocade robe and armour". That is, the upper body wears brocade robes and the lower body wears armor. This way of dressing mainly appeared in the military parade or important ceremony of the ancient emperor, aiming at showing its majestic, noble and elegant image. This way of dressing is not common in modern times. Armor is an ancient battle suit used for defense. Made of metal or other hard materials, including helmet, chest protector, shoulder pad, arm protector, hand protector, leg protector, foot protector and other parts to protect all parts of the body.
