To be or not to be,that's a big problem.
Yes or No,another big one.
I think,to find the answer for your question is less important,compared to learning Chinese.Only when you have learned quite a lot about it can you find a satisfied answer.In other words---before you have had(mastered)it,you are not eligible to ask this question.^_^ Master it,then no matter it's useful or not,you have already had it-----it will help you when neccessary.You will find the answer then.
Know Jay Chau?It's said that someday may come when our foreigners are asked to have a Chinese Test,using Jay Chau's songs for listening comprehension and Classical Chinese reading comprehension.haha.It will be a good news~~ha.
Come on.Just do it.You will feel proud of yourself then!
