A few years ago I went to China for a few months, and I couldn't speak Chinese, and this frustrated me, so I wrote about this and had it translated into Chinese, and then I learned this by heart, like music, I guess.
Hace unos años fui a China por unos meses, y no podía hablar chino, y eso me frustró, así que escribí acerca de esto y lo traduje al chino, y luego lo aprendí de memoria, como la música, supongo.
