I am a Chinese native speaker and an English learner. For my experience in learning English, I would prefer to choose some "critical" key words to refine as those words are very important to connect words into a useful sentence. For example, "engage", "employ" are 2 important words I learned not only  knowing the mearning in a a long context but also checking it up again in dictionary to see those examples listed in books. Do not focus on too abstruse English words and neither in Chinese characters.

Let's back to your Chinese (my mother language), it is not deserving of you to master those abstruse Chinese characters. If possible, enough time, check those keywords as many as you can in dictionary to see how it is expressed in examples. That would be very helpful to my knowledge.

There are several keywords I can note here:

可是、虽然，相信、

The advice from the Hacking Chinese blog is to take the following approach.  If you come across a new character or new word, look it up so that you understand the sentence, but don't bother learning the new character or word.  If you come across the same character or word a second time, then you should pause to learn the new character or word.  That seems a sensible suggestions.

Of course memorizing them is better and important:)

Thank you Alister, then I should learn it just like any other language, sounds logical
