Old Master Zhang now finds himself increasingly at a loss for how to comfort his grandson. Perhaps as time goes on, these matters have become deeply rooted in his grandson's heart, with no way to change them. He knows that the conclusion of everything now is merely the result of his own son's decisions, and there is no way for him to alter the mistakes his son had made; thus, he must bear the responsibility himself. There are no such good deals in this world.
"Grandpa, I understand all the reasons you've mentioned, but these issues have become deeply entrenched in my heart. I can't easily let go, don't you know that? My mom and dad abandoned me, their own son, when I was only a month old. How could I, as their son, feel okay? I am a living, breathing person too. I've yearned for my parents to be by my side. I've endured too many years; I've even become numb because I've continuously suppressed my feelings.
