Man’s strength wanes with age.

人的体力随着年龄的增长而衰退。

It wanes because you forget about death.

本源衰退是因你忘了死亡.

The moon waxes and wanes each month.

月亮每个月盈亏一次。

The moon waxes and wanes.

月有盈亏圆缺.

As vice wanes, virtue waxes.

锄一恶, 扬十善.

Youth wanes year after year;

青春一年一年地消逝；

The moon waxes and wanes every month.

月亮每个月都有盈有缺。

The moon waxes and wanes, so do people.

月盈月缺，人亦如此。

The moon will become full after it wanes.

月缺以后会有满月。

The moon suddenly wanes and flowers shut.

霎时间月缺花飞。
