Why did Qin Mugong the three sages, Ziche die, Ziche Zhongxing and Ziche Chenghu were martyred

There is no clear statement in history.

For the funeral of the three sages, some people say that the three brothers volunteered to accompany the funeral, and Qin Mugong's death hit them very hard, so they went with Qin Mugong.

But there is also a saying that Qin Mugong was afraid that after his death, the three brothers of the Ziche clan would be too virtuous and intelligent, and they would be loved by the people, which would affect the stability of the royal family and threaten the development of the royal family, so he asked the three of them to be buried together to prevent future troubles.

Ziche Zhongxing (?) —621 BC), a doctor of the Qin State during the Spring and Autumn Period, is said to be a warlike general, known as the "Defense of the Centurion".

The sub-car is dying (?) —621 BC), a doctor of the Qin State during the Spring and Autumn Period, is said to be a warlike general, known as the "special of a hundred masters".

Sub-needle tiger (?) —621 BC), a doctor of the Qin State during the Spring and Autumn Period, is said to be a general who can conquer and fight, and is known as the "Emperor of the Centurion".

Poetry, Qin Feng, Yellow Bird.

Crossing the yellow bird, stopping at the thorns. Who from Mu Gong? The sub-car is dying (?) This is dying, the special of centurions. In its hole, I am worried. The sky of the sky, annihilate my beloved! If it can be redeemed, people will be in a hundred places!

Handed over to the yellow bird, stopped at the mulberry. Who from Mu Gong? Ziche Zhongxing (?) Maintain this mid-line, the defense of the hundred. In its hole, I am worried. The sky of the sky, annihilate my beloved! If it can be redeemed, people will be in a hundred places!

Handed over to the yellow bird, stopped at Chu. Who from Mu Gong? Sub-needle tiger (?) This needle tiger, the king of centurions. In its hole, I am worried. The sky of the sky, annihilate my beloved! If it can be redeemed, people will be in a hundred places!

In 621 BC, Qin Mugong died, and 177 people were killed in his will, including the "Sanliang" loved by the people, that is, the three brothers of the Ziche family, also known as the three Liangs of the Che family. The people hated this atrocity and deplored the death of Sanliang and wrote this poem. The most well-known deeds of the three sages are probably this.

There is a view that the three sages wanted to follow Qin Mugong to accompany the funeral, and there is no historical evidence, and there is also a theory that Qin Mugong was afraid that after his death, the Ziche clan would be too virtuous, and people would love them too much and affect the stability of the royal family, so they were buried together by the way.

To be honest, about these three, I think unless you are a senior historian can say one, two, three, too little information, maybe you need professional books to have their information, I have only read the Eastern Zhou Dynasty Chronicles, but why did Mu Gong want the three people to be martyred, there are two reasons, one is that he is afraid that after Mu Gong's death, the three of them will be high, which is not conducive to the rule, and the second is that Mu Gong wants to be the emperor underground after his death, so that the three of them can continue to assist him, and at that time, the Qin State did have the custom of burial of the living

Passing by, marking, waiting for the master's answer.

However, the information on the three bosses you mentioned is really very small
