There was no obvious mistake in the grammar of this sentence, but there might be some problems in the expression that needed to be corrected. The proposed revised sentence is as follows: Reading a large number of excellent literary works could not only increase knowledge but also enrich emotional experience. The reason for the change was that the "and" and "can" in the original sentence used a parallel relationship. However,"enrich one's feelings" was not a complete sentence, so it needed to use a conjunction to connect the two parallel components, namely "not only can" and "can". At the same time, in order to make the sentence clearer, he could also change the phrase "increase one's knowledge" to "increase one's knowledge" or "improve one's knowledge level" to highlight the benefits of reading literary works.
