Ningguo has four sons, the eldest son Jia Daihua, who is Jia Zhen's grandfather. Jia Qiang's great-grandfather is undoubtedly Jia Daihua's younger brother.
In A Dream of Red Mansions, there is not much ink about Jia Qiang, except that his parents died young and lived with Jia Zhen in Ningguo House since childhood. Jia Rong's peers, similar in age, study in the same place. Therefore, even fighting cocks and running dogs, enjoying flowers and reading willows, or even playing pranks, are all interested in the same thing.
Brief comments on characters:
Jia Qiang, a decent great-grandson of Ningfu, whose parents died young and lived with Jia Zhen since childhood, is now sixteen years older and more handsome than Jia Qiang.
Jia Qiang is very generous. On the thirty-sixth trip, Jia Qiang spent 128 yuan to buy a bird in order to please the Lingguan. Unexpectedly, this "Jade Top Golden Bean" not only didn't make Lingguan happy, but made Lingguan very sad, saying that Jia Qiang teased himself with this bird. I was so anxious that Jia Qiang swore, even the cage was torn down, leaving the bird alive.
