It must have been that letter that deceived her, or rather, Shangguan You who deceived her. If it weren't for that letter from her, how could he have believed that Cheng Li was his granddaughter?
So, if anyone is to blame, blame that damned woman, Shangguan You. If she were still alive, he would definitely teach her a good lesson.
Old Jiang found a scapegoat for his mistake, and felt a little better. He placed all the blame on Shangguan You, believing it was all her fault.
Otherwise, how could he have thought Cheng Li was his granddaughter?
Never mind, the mistake has already been made, and now he can only let it be. Otherwise, the Jiang Family's face would really be gone.
While thinking about this, Old Jiang stood up, preparing to see off the guests. Just then, Old Madam Jiang walked over, looking at Old Jiang's unpleasant expression and asked, "Dear, what's wrong? Why do you look so upset?"
