We read all the lead to present a different history.
Speaking of the Three Kingdoms, many people are very familiar with it, and there are many talents in the Three Kingdoms period, many of whom have left a strong mark in the history of the Three Kingdoms. The Three Kingdoms era is also a typical chaotic world, which is called "creating heroes in the chaotic world", so the Three Kingdoms period has always been a more popular era for people, but the Three Kingdoms chaotic world is competing for deer in the Central Plains, why was there no foreign invasion at that time? Only because one person guards the border pass.
This person is the leader of the Western Liang Army, Ma Teng, everyone is not very familiar with Ma Teng, but when it comes to his son Ma Chao, everyone is very familiar with it, one of the five tiger generals of the Shu Kingdom, who has made great contributions to the Shu State, Ma Chao's bravery even Cao Cao is amazed, saying that if Ma Teng's son does not die, he will die without a place to bury, as the saying goes, "Lao Tzu hero is a good man", Ma Chao is so brave, naturally not less influenced by his father Ma Teng.
Ma Teng, after the Han Dynasty General Ma Yuan, but in his generation, he was in the middle of the family road, which is still somewhat similar to Liu Bei, who is also a descendant of Liu Sheng, the king of Zhongshan Jing, and later fell in the family road to sell straw shoes for a living. Ma Teng even made a living by logging when he fell, and later Ma Teng succeeded in a turmoil with his life's strength and wit, becoming the supreme leader of the northwest frontier.
Later, Ma Teng also married the Qiang people, so that he had a certain connection with the Qiang people, which is one of the reasons why Ma Teng was able to maintain no turmoil at the border pass for decades, Ma Teng's bravery made many local Qiang people convinced, so as long as Ma Teng was there, these foreign tribes did not dare to attack the Han Dynasty, although the Three Kingdoms were a chaotic world, but Ma Teng has been guarding the border pass, becoming a natural barrier to the Han Dynasty.
As early as the time of Emperor Wu of the Han Dynasty, the emperor ordered the expulsion of the Xiongnu, and these ethnic minorities could not be effectively developed, coupled with the powerful deterrent power of Ma Teng on the border pass, these foreign tribes did not dare to use their brains. However, later we know that after Ma Teng went to Xuchang, his son Ma Chao directly launched the Battle of Tongguan regardless of his life and death, and eventually ended in failure, and the border pass was gradually neglected.
This gave the foreign people the opportunity to develop, and later Sima Yi was ordered by the Emperor of the State of Wei to encircle and suppress Gongsun Yuan, almost all of the Gongsun Yuan family was extinct, almost all the Han people here migrated, Goguryeo took the opportunity to develop and grow, in addition to the Hu people in the border pass also got a strong development, in the Jin Dynasty was in the water, the "Rebellion of the Eight Kings" broke out, and then triggered the deadly "Wuhu Chaohua".
