First, outstanding personality.
In ancient times, it was very important for the emperor to marry his sister and daughter. He was very particular about the right match. Although the folk customs of grassland tribes are relatively standardized, that is, relatively open, there are still some basic distinctions of honor and inferiority, which are divided into nobles and civilians. Temujin's sister was born in a noble family and never got married, but she was finally attracted by a poor boy because he was honest and kind, and he was bald. After the death of the princess, Temujin betrothed his daughter to the bald head.
Second, it is the royal family.
When Genghis Khan intended to alienate the top of Kelie tribe with alienation strategy, he sent Shuerchedan and others to carry out the task. In the process of crossing the desert, they fainted at the destination, so they met with noble baldness. Bald took them back to their home and gave them the most thoughtful care. Finally, he gave them the only horse in the family.
Third, life experience is extraordinary.
After the surgeon Che Dan and others returned to Genghis Khan, they reported this situation to Genghis Khan, who was very interested in baldness. After investigation, it was found that Botu originally came from a noble family, and it was only the decline of Jiajing that led to such a situation. But instead of falling, he developed a good skill, especially archery.
