The translation from Chinese to English is not good in some questions hence making it hard to understand the context of the question. And also one of the question was not translated, question 31.
Thank you very much, you have raised a good point. We have translated question 31.
For the translation issue, we are sorry that some technical terms are really difficult to translate, we will try to improve that.
