The grandfather referred to here is, of course, not Old Nie, whose ashes are half-buried in Mount Babao. By default, it refers to Elder Yang of the Yang family. The so-called Love for the house extends to the crows on its roof. The value Elder Yang placed on his granddaughter naturally reflected in his attitude towards Nie Zhenbang.
Gazing at Nie Zhenbang's thoughtful expression, Yang Shengli felt somewhat emotional. His son-in-law was politically gifted, but his tactics were still juvenile. For example, in the Liangxi incident, he could have reported Li Guohua's misdeeds through conventional channels, which would have also cost Li his position, and saved Shen Yanshuo the trouble of preserving the Li family's honor. That would have been a win-win situation. However, Nie Zhenbang chose a path that provoked the Li family, which was not wise and showed his immaturity.
