Lv Gong, a single father (now Shan County, Shandong Province), is a good friend of Commander Pei County. In order to avoid enemies, his family moved to Pei County. People related to the county magistrate in Peixian heard that the county magistrate's friends had come and all went to congratulate the county magistrate. At that time, congratulations were given to give money, and Xiao He was responsible. Xiao He announced to the giver: "The gift is less than 1000, please sit down." Although Liu Bang is only a pavilion leader, he is familiar with those officials in the county. Instead of sending a congratulatory message, he boasted, "I will send 10,000 congratulatory messages" and went directly to visit Lv Gong. Lv Gong was surprised to hear someone say that he would send 1 10,000 yuan as a gift. He quickly got up and went to the door to meet Liu Bang. He saw that Liu Bang had a high nose and a long forehead, so he asked him to sit down. Xiao He didn't like Liu Bang's appearance, so he exposed his background and said, "Liu Bang always talks big and doesn't do practical things." Liu Bang dismissed Xiao He's words. He still sits in the first place without shame. Lv Gong admired Liu Bang very much. He motioned for Liu Bang to stay after drinking and said to Liu Bang, "I think you will succeed in the future. I have a daughter to marry you. " Liu Bang was so happy that he married Lv Gong's daughter Lv Zhi, later Lv Hou.
After Liu Bang became the director of Sishui Pavilion, he once escorted the corvee farmers to Xianyang, Qin Dou. On one occasion, he happened to meet Qin Shihuang during a patrol and watched Qin Shihuang's majestic posture on the roadside. He couldn't help admiring: "A gentleman should be like this!" Later, as a curator, Liu Bang escorted a group of county servants to Lishan to repair the mausoleum of the First Qin Emperor. Many people didn't want to die, so they ran away. Liu bang couldn't stop when he saw it. It is estimated that by the time we get to our destination, Wisdom Fofo Agbo has run almost and he can't go to work. So when I went to osawa, west of Fengyi, Liu Bang asked everyone to stop and have a rest. In the evening, he untied the rope to prevent the servants from escaping and said to them, "Run away, all of you, and I will run away from here!" " At that time, a dozen strong servants were willing to escape with Liu Bang. Liu Bang drank a lot of wine with them, and fled to Mangshan and Dangshan (now northeast of yongcheng city, Henan Province) with the dozen people overnight, and hid. Not far from Liu Bang's hometown, Lv Hou constantly sent people to contact him and sent him the news he heard outside; People are constantly looking for Liu Bang to join their team. At this time, Liu Bang was actively preparing for the struggle with Qin.
