He Lu's tomb is located in Tiger Hill Jianchi, where Yan Zhenqing, a great calligrapher in the Tang Dynasty, once wrote four characters, each more than two feet long, vigorous and powerful. After being eroded by wind and frost, a section of "Tiger Hill" was lost, so it was carved as it was in the Wanli period of the Ming Dynasty. So Suzhou people call it "fake tiger hill, real sword pool", and some people say that this sentence alludes to the secret of He Lv's tomb.
According to local records, under the sword pool is the burial place of He Lv, the king of Wu. When he was buried, he buried his beloved 3000 swords as sacrifices in the tomb, hence the name "Jianchi". Many gold diggers in history wanted to dig the tomb of Helu. On the outside of the sword pool, there is a big stone that runs north and south, with an area of one or two acres. Legend has it that after the completion of He Lv's tomb, Fu Cha, the king of Wu, was worried that craftsmen would reveal the secrets in the tomb, so he invited all craftsmen to drink and watch the crane dance. White cranes can dance, too. How rare! They craned their necks happily, waiting for the arrival of cranes, but what they were waiting for was handfuls of cold light shining swords. It is said that there are more than 1,000 craftsmen in wyndell dichinson, and the stone is still purple-brown, so it is called "Thousand Stone". Fu Cha, the prince of Wu, used this deception to kill innocent people, which was very despicable.
