Personally, I think it's better to be broad, because if you read more things, you will naturally feel the author's meaning (of course, this "broad" does not mean that you just don't want to take the exam after reading). Some works only need to know what you have read, and there is no need to understand the representative significance of every detail; Other people's meanings are just their own opinions. Don't believe everything others say, "There are a thousand Hamlets in the eyes of a thousand people", and some meanings are even imposed on the works by readers, but the author may not think so. So you don't have to delve into reading, "Pan", you have to think for yourself.

Disk is the cornerstone, essence is the key.

Reading must be well-read and carefully crafted.

Finally, good luck!
