There are several generations in the lyrics. What song is repetition?

It was an era when Mao Amin's songs were not vernacular. There are many words such as "once a generation" and "once a generation" in the lyrics.

Lyrics excerpt: Don't live in vain, don't be tired, don't live in vain, don't scare anyone, don't live in vain, girl, that guy, don't live in vain, each generation is worse than the next. The older you live, the less you get. Living will get thinner and fatter. Living will get richer and poorer. If you live, you will be strong, and you will have strength. If you live in vain, you will get what you want. Laughter will be crisp.
