First, the Zhang Ying family attached great importance to the imperial examination system. We know that in that society at that time, the most direct way for civilians to enter the upper class was to take the imperial examination, so the Zhang Ying family attached great importance to the imperial examination education. Zhang Ying once said to his children and grandchildren: "Reading can take the name of a family, but it also makes people respect." It is precisely because of Zhang Ying's emphasis on education that his descendants will stand out in the imperial examinations and become the pillars of the country.

The second reason is that his wife Yao has educated her children well. The Yao family is a very open-minded woman, especially in educating children. She is very strict with her children, especially in thinking. She often says to her children, "We must have perseverance." Therefore, under the guidance of Yao, the children's personalities are very tough. Later, Emperor Kangxi praised Yao's family and said, "Brother Zhang, his mother teaches well, not only his father!" It can be seen that Emperor Kangxi also recognized the Yao family.

The third reason is the political marriage between the Zhang Ying family and the famous family. In ancient traditional society, marriage also pays attention to "being suitable for each other", which is recognized by both ordinary people and dignitaries. Our family is also a big family, and it is married with Yao family, Fang family and other famous families in Tongcheng. It can be said that it is powerful, and these big families have woven a huge network of relationships. It is precisely because of this that there were many officials in the Yao family at that time, and there was even a saying among the people that "Zhang and Yao were two surnames, and the gentry accounted for half."

The fourth reason is that Zhang Ying's family has formed a huge interest group through the relationship between students. In the imperial examination system, there is a teacher-student relationship among examiners, juren and Jinshi, which will never change. Zhang has served as the examiner for many times, and his proteges are all over the court.

It is for these reasons that the Zhang Ying family has produced so many talents.
