Haha Chinese is my second language. With Vietnamese or Chinese, you need "absolute pitch" to be able to speak it like natives when learning as an adult. China/Vietnam have higher proportion of people with absolute pitch. It has to do with the number of phonemes in a language. There is also a genetic aspect of it. Mandarin speakers will have higher IQ than normal population.
