Look at the origin of Qin State, and you will find the importance of mastering a skill. The Qin people were able to make Zhou a vassal state, and they also came step by step. In the early days, the leader of Qin people was just a slave who raised horses for the Zhou royal family, but he was praised by the Zhou royal family for his proficiency in raising horses, and was promoted by Zhou Wangxiao and became a vassal of Zhou Wang. At that time, the fief was Qin land.
Later, when the Western Zhou Dynasty perished, the Qin people escorted the Zhou royal family eastward and were made princes, which was the beginning of the State of Qin.
In fact, before the Zhou Dynasty, the life of Qin people was already very good. According to the present statement, people have money from their ancestors. At that time, they were nobles of Shang dynasty, living near the capital, and had already been named princes. At the end of Shang Dynasty, the Western Zhou Dynasty rose. After Wu Wang conquered Shang Dynasty, Qin people became adherents of Shang Dynasty. At this time, the adherents of Shang Dynasty still lived near the original capital of Shang Dynasty.
King Wu died shortly after completing the establishment of the Zhou Dynasty. Because he was a young king, the power of the dynasty was transferred to Zhou Gongdan. In order to manage the adherents of Shang Dynasty, the Zhou Dynasty sealed the Shang Dynasty to Wu Geng, the son of Zhou Wang, and practiced the method of "treating Yin with Yin". This move made be in heaven, a adherent of Shang Dynasty, beneficial to the stability of the newly occupied land. However, in order to prevent these businessmen from waiting for opportunities to resist, King Wu also arranged for his brothers Guan Shu, Cai Shu and Huo Shu to monitor the merchants nearby.
Businessmen began to live and work in peace and contentment, but for Wu Geng and the adherents of Shang Dynasty, they were very reluctant to lose the world. At this moment, King Wu died young, and the Duke of Zhou gained the power of the dynasty. This incident aroused the suspicion of the King Wu brothers, including Guan Shu, Cai Shu and Huo Shu, who were in charge of monitoring the former site of Shang Dynasty. And Wu Geng acted according to circumstances to win over three people, and soon the "three prisons chaos" broke out.
However, this turmoil did not cause any damage to the Zhou Dynasty. When the Duke of Zhou learned of this, he quickly led an army to conquer the East.
In this World War I, Wu Geng was killed, and Qin people, as adherents of Shang Dynasty, also participated in it. The Duke of Zhou was rude to these people, and directly moved them to the side of the King of Zhou and demoted them to slavery.
After more than 100 years of development, Fei Zi became a groom of the Zhou royal family. It's hard to say exactly how to raise horses, but his skill in raising horses must be very good, so he directly changed from a slave to a vassal of the Zhou Dynasty and was sealed in the State of Qin. Qin people gradually became the servants of the Zhou royal family, guarding the capital for the son of heaven.
In the battle with Xirong, the Qin people were once again named doctors.
At the end of the Western Zhou Dynasty, Zhou Youwang acted recklessly, resulting in the destruction of the city and the loss of life. Since then, Prince Yijiu has succeeded to the throne with the support of the governors. In order to avoid foreign invasion, Zhou Pingwang chose to go east to Luoyi. At that time, Qin Xianggong, the leader of the State of Qin, was made a vassal for sending troops to escort him. In addition, it not only gave Qishan, the birthplace of Qin people and Zhou people, but also promised that as long as Qin people defeated Rong, all the land would be owned by Qin people. Since then, the Qin people have waged a long war with Rongren.
To sum up, if the trajectory of Qin people is wavy, from vassal to slave to vassal, it can only be said that fate fluctuates.
