"What animal does the Great Wall of China look like?"
Why would it look like a chicken? I've only heard that about the geographic shape of the country (and of other countries too, strangely). The Great Wall looks like a dragon: Long, snake-like, and powerful.
It's the dragon (Chinese's dragon has the long body likes the snake's body, not likes Europe's dragon).
Sometimes punctuation doesn't seem to be ignored in the Chinese course, so probably because of the period instead of a question mark.
