A happy life is earned by oneself, not given by others!
In fact, Old Master Zhang knows very well that he no longer has any right to interfere in the household affairs between his grandson and granddaughter-in-law. He also understands that everyone needs to grow, and only through continuous growth can one's life become meaningful. Initially, his own growth brought many painful memories, but these eventually became the most beautiful memories within him. Regardless of which industry he ultimately chooses or what experiences he encounters, every choice he makes will bring joy for what he has once contributed, without leaving any regrets.
