Why did Hou Jichang, a Xibe nationality, ask Sanyezi to interpret his dreams? Doesn't he know divination himself?

Xibo Hou Jichang's search for the son Yi to interpret dreams may have many explanations. First of all, although Xibo Hou Jichang is a person with divination ability, he may think that his understanding of dreams is limited and he needs a more professional dream interpreter to help him understand the meaning of dreams.

Secondly, Sheng Ziyi may have unique experience and knowledge in dream interpretation, which can provide the professional guidance needed by Xibo Hou Jichang. Sometimes, even if we have some professional knowledge, we will still seek the opinions and help of others to get more comprehensive and accurate answers.

In addition, Sheng Ziyi may have a special relationship with Hou Jichang of Xibe nationality, which gives them a basis for mutual trust and cooperation. When people choose to seek help, they usually consider each other's reputation, experience and professional ability, as well as their close relationship.

To sum up, Xibo Hou Jichang may choose Sheng Ziyi to interpret dreams, because he thinks Sheng Ziyi has more professional ability and experience in interpreting dreams, or for other personal or relationship reasons. But the specific reasons can't be accurately judged, because we can't directly understand the specific situation and background at that time.
