Qiao Zhicai, though reluctant to part with his little grandson, had to leave for Yun City.
Doudou and Feifei had started at a new school and needed to adapt. As transfer students, they were falling behind, so a tutor was hired.
The children's studies became intense, and they needed someone to fetch them to and from school.
Both Qiao Genbao and Niu Guili had low educational levels, so both had enrolled in night school. Therefore, the task of transporting the children fell to Qiao Zhicai.
Following Mr. Wu's suggestion, they considered buying a car specifically for the two children's commute; however, Wu Qianyun rejected the idea.
The children were still young and, even with a wealthy great-grandfather, should not develop the habits of young masters and mistresses.
Qiao Zhicai readily agreed.
