In this lifetime, people live in this world to ensure their lives aren't so monotonous. No one wishes to live unchangingly, and no one can continue living like that forever.
Zhang Yichen now feels that his father's experiences over the years outside truly represent a colorful life. These experiences he hasn't had, he also wants to go out and roam a few times, to live recklessly for himself across the horizon. But these years, in pursuit of his goals and to prove to the world that he is a good man, he has forgotten what he ultimately wants.
"Dad, do you know? When I hear you talk about your life experiences, deep inside, what I feel most is envy. I admire you even more, for you can whimsically live outside for so long, disregarding everything at home to live freely just for your happiness, whereas I can't. My whole life has been spent running around for the entire family's sake, and I never knew what it's like to live alone. I haven't even tried to know how to live independently."
