Longquan Sword Baidu has said: The fifth of the ten famous swords in ancient China, a sword of integrity and purity. Legend has it that it was forged by two great swordsmen, Ou Yezi and Ganjiang. Ou Yezi and General Qian made the sword, cut open the Cishan Mountain, released the mountain stream, and led it to seven pools surrounded by the Big Dipper next to the sword-making furnace, which are called "Seven Stars". After the sword is completed, looking down at the sword body is like climbing a high mountain and looking down into the abyss. It is ethereal and deep, as if there is a giant dragon lying on it. It's called "Long Yuan". Therefore, this sword is called "Seven Stars Long Yuan", or Long Yuan Sword for short. In the Tang Dynasty, in order to avoid the taboo of the great ancestor Li Yuan, the word "Yuan" was changed to the word "Quan", and it was called "Seven Star Longquan", or Longquan Sword for short. Today, watch me drinking wine and talking happily about Longquan. . .
