"Parents give their children everything, but children may not even return a fraction to their parents."
The saddest thing in the world is having nothing to depend on in old age. For Accountant Zhang, his five sons were his pride and joy. He had sympathized with lonely elderly people he met, but never thought he would find himself in a similar predicament one day.
If it weren't for his youngest son, how would he be any different from Mr. Zhang? He could never understand why, after working tirelessly and risking their lives in those turbulent years to raise five sons, now, except for the youngest, the other four sons seemed to have forgotten the hard times and their upbringing.
In the dead of night, he felt the sadness. He could only comfort himself by thinking that they wouldn't understand the struggles of their parents unless they become parents themselves. Someday, they will appreciate how difficult life is for their parents.
