1227, after the death of Genghis Khan, the third son of Bo'er Only Jin Wokoutai, the third son of Tuo'er Jin Wo kuotai succeeded to the throne and Tuolei oversaw the country. In 1232, he led an army to defeat the Jin army, but as a result, he died of illness on the way back to the army. There is no doubt that Tore is the most capable militarily of Genghis Khan's sons.
However, after Tuolei's death, Krey Ruhothini took charge of the Tuolei family. At this time, Wokoutai did two things, which made the people suspicious of him. In fact, putting these things into the background of Mongolia at that time, in my opinion, are two very normal things.

The first thing was to ask Thore's daughter-in-law, Krey, to marry her eldest son, Guiyu, as his daughter-in-law, but she refused on the grounds that her sons were not yet adults. However, this was a very normal thing in Mongolia at that time, because in their concept, there was never a concept of "generational division", and the daughters-in-law were snatched by themselves.
Therefore, it is very reasonable for Wokoutai to grab a daughter-in-law for his son, and as for the relationship between this daughter-in-law and himself, there is no connection at all. It can be said that at that time, let alone robbing one's own sister-in-law as a daughter-in-law, even if it is robbing one's own sister-in-law as a daughter-in-law, it is a very normal thing.
The second thing was this: Wokoutai asked Krie Torohetini to give a little wealth from Tuolei's family property to his second son Kuoduan. There were only three thousand households given, although this was quite a lot for outsiders, but if it were placed in the actual wealth of Tuolei, these three thousand households would be equivalent to a little fur at that time.
In fact, having ninety-six thousand of Genghis Khan's one hundred thousand households is only a little bit for these three thousand households, moreover, wokoutai does not want much, three thousand households is reasonable. Moreover, if these three thousand households are placed among ninety-six thousand households, the proportion is almost negligible.
Therefore, how can it be said that "Wokoutai is going to annex the army of Tuolei"? If Wokoutai were to annex Torre's army, he would have to go through most of the ninety-six thousand households. Moreover, the three thousand households that came to this were not so easy to ask for. Three thousand households that had been divided from these ninety-six thousand households, their soldiers did not want to come to Wokoutai at all.
Since they didn't want to come, they would make trouble, and after that, there was a fierce confrontation between them and Wokoutai. When Wo Kuotai saw this situation, there was no way, and in the end, it was only by the wise instigator Lu Hetiani to come forward to persuade them to stop the three thousand household soldiers. After that, they went to Wokoutai.
However, it should be fortunate that the soldiers of these three thousand households were making trouble in Mongolia, if in the Central Plains, the soldiers of these three thousand households would have been killed by the Han emperor many times. Therefore, wokoutai wants to annex the army of Tuomin, which is simply not proof. As far as the three thousand households are concerned, what can be done to deal with the remaining ninety-three thousand households?
In fact, the two things that Wokoutai did were very normal, but they were confused by the demons and made it difficult for them to speak, so that to this day everyone thinks so.
The Mongols have a tradition, that is, no matter how poor they are, they will not rob their own families of a penny, they will only rob outsiders of their money, so how can wokoutai, who is with the Toure family, have an idea of Tuolei's property. If you want to rob property, you can only join forces with others to rob other people's property. What's more, what Wokoutai wanted from Tuolei was still for his son, and he did not seek any benefit for himself at all.
Helu Hetiani was originally the wife of Tuolei and had outstanding management skills. Moreover, she was also the biological mother of Möngke, Kublai Khan, Hulagu, and Ali Bu brother. Because his sons had all been emperors, she was also called "the mother of the four emperors" by later historians. From here, we can also see that this woman is still very powerful.
But if that was the case, then what else did he let Lu Hetiani marry?
There are two reasons for this:
First, it was because Wo Kuotai wanted her to come over and help her indisputable son Guiyu.
Second, he felt guilty about Tuolei and asked Lu Hetiani to come over, also in order to use the relationship between the superior and the pro to make up for them.
In addition, when WoKoutai asked Lu Hetiani to marry, he did not let her bring her son and property with him. Moreover, at that time, Tuolei's four sons had reached the age of adulthood, and some of them even had to catch up with Guiyu's age, so how could they go over to Guiyu as sons. For property, we have analyzed it before, and Wokoutai does not have the mind of annexation, so how can it be the idea of towing thunder.
However, WoKoutai is actually quite sad, as a big khan, when he wants to give his son something, he is empty-handed, he can't get anything out, and in the end, he can only ask others to ask for it. As a result, these people were unwilling to give, and it took a long time to give it to WoKoutai, and in the end, they slandered Wokoutai as ambitious, and even made up such a ridiculous thing as Wokoutai wanting to annex the Tuolei army and property.
If this matter is placed in the hands of the Han emperor who has concentrated power in one, I would like to ask, where are these things? In fact, this is only because of the dispute caused by Mongolia's special system, and Wokoutai actually did not think so much. Therefore, when drawing conclusions about a historical event and person, we must synthesize various factors and consider them comprehensively before drawing conclusions.
Moreover, after the death of Wokoutai, Queen Naima zhen wanted to establish his eldest son Guiyu as the Great Khan, and Batu and Guiyu refused to participate in the election of khans, and later, Genghis Khan's younger brother Temuge Chijin also led troops to fight for the throne, and the empire faced the danger of civil war and chaos. Instigating Lu Hethini decided to lead her sons to the assembly, and, with the ascension of Guiyu to the throne, stabilized the situation and further increased her prestige.
