“con rồng, cháu tiên”: “child of dragons, grandchild of immortals”.
This one refers to an old tale: according to legend, the Vietnamese people are descended from the union of the dragon Lạc Long Quân and the immortal Âu Cơ: they had a hundred children together, but because they were so different (he was a dragon from the deep seas, she was an immortal and only felt at home in the mountains), they ended up separating. Lạc Long Quân, summoned home by his mother, took half the children and went towards the sea; and Âu Cơ took the other half into the mountains. This was the origin of the Vietnamese people.
I am currently learning preposition and interrogative words (the words that you tack on the end of a sentence to signal that it’s a question. Yup, it’s a tonal language, which means that raising your voice at the end of a sentence just results in your mangling the last words by giving it a rising accent…). Not exactly fun, but necessary.
