Chinese
Well I'm a Chinese live and grow up in Beijing, so Chinese shouldn't be difficult for me. But unfortunately, our Chinese exams always make me crazy!~ Every character may have more than one pronouciation or meaning. And when you use, you have to figure out each one. And they always give you similar characters or ambiguity words and ask you which is wrong. I really hate that!
What's more, Chinese has a long history, so it means that if you only learn contemporary Chinese, you can't fully understand dialogues. We learn old Chinese reading, and have to remember each character's meaning and useages. Many words we use today comes from old words or stories which you have to remember. And ancestors did grammar differently from nowadays, so, remember both old and new
If you want to read something from HongKong or Taiwan, you also need to know Traditional Chinese.I learnt that by reading comics~
But don't worry, since China has thousands of accents(southern has more than the north), locals, especially city people, are used to strange Chinese~~~And if you learn mandarin well, you can talk with most people here(students all learn mandarin at school).
Japanese
It's very useful when you read comics or watch cartoons or listening to music. But it's similar with Chinese(Japanese learnt form Chinese some how in history). It also has charactors, but a little different from chinese.
I think it's difficult for me because I'm not sure if I can still remember how to speak and write Chinese correctly after learning Japanese~~~One of my school teachers did make a lot of mistakes when she speaks, after spending 3 years in Japan~
French
I may make more mistakes in English and can't pronounce English well after learning French~ English is the subject I must learn well and I did learn better than a lot of other students~especially my British pronouciation~ And I don't think French sounds wonderful...
Middle East languages
I can't remember those long sentences just for 'hello'~_~
hope what I say can make you know Chinese better~~~~~~~
