Girls in love are always a bit silly, which made Xu Qing somewhat unable to distinguish whether Jiang He was inherently simple-minded or if she just became less intelligent when she was with the person she liked.
Jiang He had never gone to school, and he was very aware of this. He also tried his best to understand the kind of thought process that came with never having received an education.
The Accountant that Jiang He had casually mentioned seemed to be cultured, but at most he just taught her how to read.
Self-positioning, self-awareness, and the understanding of the outside world—Xu Qing had been consciously and unconsciously helping Jiang He fill those gaps. Fortunately, even without formal education, Jiang He usually had clear logic and was methodical, which is quite rare.
This must be attributed to the stepmother, who, despite being old-fashioned, was not ignorant.
