The so-called "with a virtuous wife, a husband suffers less adversity." Marrying a virtuous wife benefits three generations, and though Cheng Su, whom Qi Taiguo married, may have a temper or be somewhat selfish, she is absolutely appropriate in general.
Since ancient times, marriages, especially among wealthy families, are arranged for the sake of family interests. In choosing a wife, one must consider how much benefit she can bring to the family. If this is achieved, nothing else matters much.
As for Cheng Su, the wife of Qi Taiguo, she not only brought him a life free of worries but also provided support. Is this not fortune?
The Ning Family, it can be said, aligned with the Cheng family because of Cheng Su, and as for the Cheng Family, that goes without saying.
The Ning Family's view of Cheng Su might also have been influenced by the admiration and liking of Old Master Ning, but there was undoubtedly a hint of interest involved.
