"sword of the yue maiden" is just a folk legend, but at the end of the Spring and Autumn Period and the beginning of the Warring States Period, the sword-casting technology of Yue was unique in the world, which is a fact. Jian Yue is called the number one in the world because it has Ou Yezi. Ou Yezi was a Vietnamese from the late Spring and Autumn Period to the early Warring States Period, the originator of ancient China sword casting and the founder of Longquan sword. Ou Yezi has cast many famous swords handed down from ancient times, and the other two swordsmen, Mo Xie, are his daughter and son-in-law.

Later, the State of Wu attacked the State of Chu, and the State of Yue was destroyed, so the last eight famous swords went to Gou Jian, the King of Yue.

Suzaku: It is said that the sharpest sword is 3 feet long, the handle is 7 inches long and the blade is about 5 inches wide. Its shape is blunt and thick, and its material is copper and tin. Legend has it that Gou Jian, the king of Yue, sat on the terrace when the butcher knife was just formed. Suddenly, a carriage in the palace lost control and rushed over to scare away the white deer in the palace. So Gou Jian, the king of Yue, pulled out the giant que sword that Ao had just dropped, pointing to the chariot and rampaging. He wants the Warriors to stop this. But when he drew his sword, the sword in his hand cut the carriage in two. Then, Gou Jian ordered another man to get a big copper pot. He stabbed a big hole in the jar with this sword. As easy as cutting rice cakes. That's why Juque got its name.
