I will try to translate this so our english speaking forum can read it:
The passage reads something like:

"The younger sister of the mountain gathered the tea,
in the plains your betroathed cut the reeds,
which caused the mandarin ducks to undertake flight alongside (each
other),
quickly the little sister and your betroathed formed a couple."

I'm completely sure of the first two lines, but the last two lines
confuse me (especially why the word "ducks" appears), however, this
seems to be a translation from chinese to spanish, so it might make
more sense in context. My translation probably isn't perfect either,
I'm not exactly fluent, and this may have some words different from the
south american spanish I'm used to.
