Chu bronzes are made in at least three places. The first research institute, headed by a doctoral student who graduated from a famous domestic university majoring in casting, organized a group of highly educated professionals, specializing in high imitation and sales of Chu bronzes. The high imitation is mainly swords, among which Gou Jian, the king of Yue, has the most swords, and the appearance and quality are enough to be called genuine. On 1965, the sword of Gou Jian, King of Yue, was unearthed in the Chu Tomb of Wangshan, Jiangling, more than 30 kilometers outside Jingzhou. Mr. Guo Moruo verified the inscription of the sword as "the self-propelled sword of Gou Jian, the King of Yue". This sword has been exhibited in Japan and Europe, and the insured price is nearly 100 million yuan. It is the national treasure of our country, and it is in the Hubei Provincial Museum. The high imitation of Gou Jian's sword is mainly sold to domestic entrepreneurs, rich administrative cadres and celebrities, as well as overseas mainland investors. If the buyer of this sword can see through the high imitation, he will immediately resell it to others, or take it to a stall for sale, so as not to be ashamed.
This was found on Google, "It is the national treasure of our country, hidden in Hubei Provincial Museum", which means it is now in Hubei Museum.
Jingzhou Museum has more than 3,000 pieces. Gou Jian, the King of Yue, is famous for his service and bravery. The sword he used was unearthed in northern Jingzhou in 1965.
This is an article introducing Jingzhou Museum. Gou Jian's sword was unearthed there and must have been stored there for some time.
So you are absolutely right!
