We all know that before Liu Bang became emperor, he was born relatively ordinary, just a small pavilion chief, still very old and even did not work every day, simply a small street, and it was in a situation like Liu Bang that Lü Gong married his daughter Lü Yan to Liu Bang.

According to the records of the history books, after Lü Gong met Liu Bang, he thought that this person had a good face and could achieve a career in the future, so he married Lü Yan to Liu Bang. But if we think about it, we will find that this statement is unreasonable. First of all, Lü Gong was a relatively wealthy family, but in order to avoid the enemy family, so the whole family moved to Pei County.
How could such a large family arbitrarily marry their daughter to a person who had nothing because of the problem of appearance, and Liu Bang was already 40 years old at the time, and Lü Yan was less than 20 years old, the age difference was so large, Lü Gongguang made such a decision because of such a superficial reason, it was very unreasonable. So there is only one possibility, and that is that there are other more important reasons.
In fact, if we put ourselves in the shoes of Lü Gong and think about it, we can understand his approach. It is worth noting that Lü Gong moved to Pei County because he avoided the enemy family, that is to say, in Pei County, Lü Gong was just a foreigner. If you want to establish a good foothold in a foreign country, you must rely not only on strong financial ability, but also on a huge network. Although the county orders of LüGong and Pei County were good, we should note that the county system of the Qin Dynasty at that time was not perfect, and many county orders were transferred from the central government to the localities, that is to say, most of these county orders were also foreigners.
This is also an important reason why many county commanders in the late Qin Dynasty were the first to be killed by the local rebel army. Therefore, if Lü Gong wants to establish a strong network in Pei County, it is not enough to rely on a county order, but also rely on real locals. And Liu Bang is a good candidate.
Liu Bang's four brothers still have a relatively large influence in Pei County, although Liu Bang is not a serious person, but he is proud, so he has also made a lot of close friends in Pei County and has deep network resources. Not only that, he also made friends with the elites of Pei County, and Zhang Liang was a good example, and he had always had a close relationship with Liu Bang.
If Liu Bang can be allowed to become his son-in-law, it can also be regarded as having a solid backer in the local area, why not let Lü Gong be happy? In addition, Lü Gong knew that at that time, the society was in a turbulent situation, and soon the world would certainly not be able to avoid war, and people like Liu Bang would definitely seize this opportunity and make a good career, which was also relatively promising.
Therefore, Lü Gong married his daughter to Liu Bang, which was entirely for the sake of the entire Lü family. He knew that Liu Bang already had his own illegitimate son Liu Fei before he was married, and he also knew that Liu Bang was very old, but he still married his daughter for the sake of the whole family. It can only be said that Lü Gong did not consider whether his daughter was happy after marriage, and in his eyes, his daughter was just a means to stabilize his social status.

Lü Gong knows that if a family wants to last for hundreds of years without declining, it depends not only on the so-called luck or strength, but also on having a long-term vision.
