Wokuotai is the most politically talented of Genghis Khan's four sons. In his later years, Genghis Khan declared him an heir in order to break the rules of inheritance for the youngest son of Mongolian tribe. Wokuotai lived up to Genghis Khan's expectations, perished the Jin Dynasty and sent troops to attack Eastern Europe. Politically, Wokuotai abandoned national prejudice, took Khitan Lu Yechu as prime minister, and used Han civil servants to rule the country by Han, which further strengthened the strength of the Mongolian khanate and laid the foundation for Kublai Khan to establish the Yuan Dynasty later.
But in sharp contrast to his political ability, Wokuo Tai is very insidious and heartless. Because the people of the Ivo tribe were very scared when they heard that Wokuotai would use their women to marry men of other races, they soon married all their girls and didn't want them to be requisitioned by Wokuotai. Wokuotai was very angry when he learned that. He led the troops directly to the Youthorn tribe, and gathered all the women over the age of seven, even the married ones, totaling more than 4,000 people.
Then Wokuotai ordered the soldiers to ravage these women, and the male relatives of these women should watch and not cry. Some women were spoiled to death on the spot, and some were taken away by Wokuotai himself and given to the minister's bodyguards to directly serve as official prostitutes. Such cruelty is rare in the world.
