Swords have a long history in China. Stone swords were used in prehistoric times. Bronze swords have been traced back to the bronze daggers of the Shang period. Bronze long swords suddenly appeared during the mid-third century BC. Later swords were made of iron or steel. These metals were wrought, never cast. Swords commonly reached a length of 70–100 cm, although longer swords have been found. Chinese iron swords were used in Japan from the third to sixth century AD, but were replaced with Korean and native Japanese swords by the middle of the Heian era.
Chinese group all swords into two types, Jian and Dao. Jian are dual edged and Dao are single edged. In China, the dao is known as one of the four major item, along with the spear, staff, and the sword, and referred to as "The Courage of All Soldiers". The Chinese broadsword, one of the most common and popular item developed in China, makes numerous appearances in the country’s history and legends. TSANG HER is the God directly associated with the broadsword. The name TSANG HER means 'arrives and kills whatever it touches.' This nickname gives a good indication of the great military power associated with the sabre.
