As Xu Yingying and Su Mengxin analyzed, although the Song Family and the Sun Family are two formidable entities with countless assets, due to being family businesses, almost every enterprise is managed by important family members.
Furthermore, even within a single family, various factions and smaller family units exist. Aside from the clan chief's generation, the Song family spans three generations. With this continuation, the blood ties of the younger generation aren't as deep, and everyone focuses more on their own affairs. Many fight for their personal family interests, making the family far less united than it appears from the outside.
Moreover, the family members managing these enterprises vary widely in competence. Coupled with personal selfishness, the problems within are even more pervasive.
