Yes, there are two stories. When Han Xin told Liu Bang to swear to seize the country one day and not to hurt himself with metal sharp objects, Liu Bang proclaimed himself emperor and ordered someone to stab him alive with a bamboo stick.

Second, when Liu Bang ordered people to ask the truth with a famous blade, he spent a year in Han Xin.

(Begging for Heaven: It is said that when Ou Yezi, the master of sword casting in the Warring States Period, was casting a pure Jun sword, the cold iron used for casting the sword was one catty and two ounces, so he hit the dagger by the way. After the dagger was cast, it suddenly began to rain red. Ou Yezi didn't know what was going on, so he named the dagger "the true man". Later, this dagger became a precious blade of the royal family, which was specially used to kill the "minister". It is said that Liu Bang promised Han Xin not to kill with a knife. So he stabbed Han Xin alive with a bamboo stick, but in the legend of unofficial history, the bamboo stick was just a smoke screen for Liu Bang. In fact, Han Xin was executed in the year, and this "candlestick" was used for the execution. In the Song Dynasty, the torture of Ling Chi was once abolished, and the "candlestick" became a court plaything. At the end of the Ming Dynasty, it was this "candlestick" that killed the famous Yuan Chonghuan.
