Old Master Zhang feels that now he should tell everything to his children, whatever it takes. He cannot let his children live as freely as before. He should shoulder the responsibilities that belong to him. Everyone living in this world has their own matters to attend to, so why cling to past incidents repeatedly? If that is truly the case, then what is the meaning of existing in this world? No one has ever thought about what all this is ultimately for?
Maybe everything he did in the past was wrong, but he always wanted his life to be happy and joyful. If he repeatedly forsakes the things he least wanted to give up for those reasons, then, no matter what, there is no way to understand or accept it in this lifetime.
