A ancient Chinese sword. Sword of Goujia, a sword which was made 2400 years. Its master, Goujian, was the king of Yue around 490 BC, during the Spring and Autumn period. The sword was found in a tomb in Jingzhou, Hubei province, in 1965. It is made from copper and tin and looks brand new though it has endured 24 centuries under the earth. It is so sharp that can easily cut 16 layer of paper. The sword is a Category I Historical Relic. You can go to Wuhan and visit Hubei Museum to see it. By the way, the other things in that museum will shock you as well.(1.1K)

一把中國古代的劍。勾踐劍,有2400年的歷史。這把劍的主人勾踐是大約公元前490年春秋時期的越王。這把劍是1965年在湖北省荊州的一座墳墓中發(fā)現(xiàn)的。它由銅和錫制成,雖然在地下已經(jīng)保存了24個世紀,但它看起來還是全新的。它非常鋒利,可以很容易地切割16層紙。這把劍是一級文物。你可以去武漢,去湖北博物館看看。順便說一下,博物館里的其他東西也會讓你震驚。
