Being born is easy; being alive is easy; living is not. Every family has its own troubles. In the 1990s, it became common for people in rural areas to leave home for work, and more and more children were left behind in every village. These children faced hardships unlike those of their peers, both in daily life and in their pursuit of an education.

Though he endured trial after trial, A Shui continued to face the sun and keep growing.
