The Lv Zhi family went to Pengcheng to find Liu Bang, but the Han army was defeated in the battle of Pengcheng, and Liu Taigong and Lv Zhi were separated from their children. Liu Bang's son and daughter were lucky enough to meet Liu Bang during the flight. Liu Taigong and Lv Zhi were captured by Chu Army on their way to escape.

Lv Zhi and Liu Taigong were held hostage in Xiang Yu's military camp for 28 months. In the fourth year of Han Dynasty, Xingyang confronted each other, and Xiang Yu suddenly had a whim: threatening to cook Taigong and forcing Liu Bang to surrender. Liu Bang refused to accept this and said to Xiang Yu: Xiang Yu and I were both ordered by Chu Huaiwang to cut Qin and become sworn brothers; So, my dad is your dad, you have to cook your dad, and I'll have soup with you. Xiang Yu was furious and wanted to cook the squire. Thanks to Xiang Bo's efforts, Xiang Yu didn't kill the squire.

Liu Bang and Xiang Yu confronted each other in Xingyang for more than two years. Due to the shortage of rations, Xiang Yu had to agree to the gap proposed by Liu in October of five years. Liu Bang tricked Xiang Yu into releasing Gong Liu and Lv Zhi who had been kidnapped for two years and four months, and then retreated. So you should be talking about Xiang Bo. The name upstairs is wrong. It's called Li Yiji.
