I think you are trying to describe a book written in Chinese that is about translation? If so, I would say grammatically you are using the passive voice and it needs to be more concise. Maybe something like, "Even though it is written in Chinese, this book confuses me. It is not about English grammar, but rather the study of translation, especially when it comes to using translation software."

To improve the English language is very challenging. I am trying to find out the best methods to reach a new level. More often that I can, I watch documentaries and movies in English, and I keep a notebook where I write down the new words I learn (phrasal verbs, idioms, etc.). I attend classes with a teacher once a week, do grammar exercises, and furthermore I sometimes speak English with my boyfriend and use some specific English apps. Nevertheless, sometimes I think that my progress is slow. Do you have any suggestion? #HelpMeCorrect #HelpwithEnglish

The main pro about online communication is the connectivity that it offers you. You can learn English easier than twenty years ago, for example speaking with somebody from other side of the world! On the other hand, one con is that you lose face to face relationships.
