I'm trying to understand an obscure pop song from the early 90s called 小鸟 by a band called 现代人乐队. You can hear the entire song here: https://youtu.be/Eef7wcIdqsc
It has a verse which goes like this:
有的人假装看破了红尘一天到晚对着墙
就是不长岁数的姑娘,她天真又大方噢
The first verse seems to be saying that there are people who pretend they've seen through the world, and spend the whole day facing a wall. It seems like these are references to Buddhism and meditation, but I feel the songwriter means people who act cool and worldly.
The next line talks about a young (immature? under-aged?) girl who is innocent and generous.
I'm trying to work out how the two lines relate. I'm pretty sure it can't be the girl who is innocent and generous who is also trying to act cool.
Could it be that the songwriter is telling the first person not to take advantage of the second person?
For reference, the rest of the lyrics are here: https://mojim.com/cny110213x1x2.htm
