Why did Wei Huanzi pass the throne directly across his son to his grandson?

In fact, what Wei Hengzi did was not wrong, because his son had already died, and he merely passed the throne to his grandson only in accordance with the system of succession of first-born sons. His son was the first-born son, if the throne was passed on to him, then his son is also Wei Hengzi's grandson is also the status of the first-born son. In fact, in addition to him there are many other emperors in history who made the same decision and passed the throne to their grandsons even though their sons were alive.

First, the Yellow Emperor

I'm sure many people know the three emperors and five emperors, these people are the same as exist in the myth, and Zhuan Xu is the grandson of the Yellow Emperor, the son of Chang Yi. And at first he was aiding the then Shao Hao, but unfortunately after Shao Hao's death **** Gong's and he wanted the seat as much as the two fought for a long time, and ultimately Zhuan Xu inherited Shao Hao's regime. He was also a powerful character, and the Xia and Chu states that followed were his descendants.

Second, Kublai Lie

He had already chosen his successor at that time, and this person was Marco Polo Zhenjin. Prince Zhenjin is also a talent, let Kublai Lie was very satisfied. But it is too good to be taken advantage of, in 1285, a courtier opened his mouth to let Kublai abdicate, will be the throne Zhenjin Prince Zen, Kublai angry. In the end, this matter was over, but the real gold Prince died of exhaustion. After his death, Kublai Lie will be the throne passed to the real gold Prince's third son, can be seen on this son is very guilty.

Third, Zhu Yuanzhang

In fact, no one than Zhu Yuanzhang did more extreme, after the death of Prince Zhu Biao, Zhu Yuanzhang's sons are still alive, according to the theory that the throne is certainly to one of the sons. However, Zhu Yuanzhang did not do so, but instead passed the throne to his grandson, the later Jianwen Emperor. It is his practice caused the "war of tranquility", which is also Zhu Yuanzhang did the most eccentric thing.
