In this video the speaker mentions a rice-planting song that goes like this:
花花铺盖几朵云哦
刚刚盖到两个人咯
But he mentions that there's another sentence on the end that he won't mention because he's on TV.
This article also basically sites the video exactly:
不只是当年陕北人民才爱这个调调。你看四川评书人李伯清爷爷说的:“花花铺盖几朵云,刚刚盖到两个人……”民歌经常是火辣直接的,天南地北都有这样的东西。
But again the last sentence is left off.
Any ideas?
