Pay attention to everything and you will learn, and the cultivation of human feelings will be an article;

This sentence is a wise saying in a Dream of Red Mansions:

The full text is as follows: A good song never tires of singing and a good book never tires of reading. Reading is expensive to doubt, and doubt can teach. Silent reading is easy to think, while reading aloud is easy to remember. If you read a good book at first, you will get a good friend; Rereading a good book is like knowing an old friend. Pay attention to everything and learn, and three people walk with my teacher.

however, this sentence is far less famous than "everything is learned when things are clear, and people's understanding is an article".

The couplet "All things are learned, and people's understanding is an article" is a traditional concept of Confucianism, which expresses the aspect of Confucianism's entry into the WTO and is also one of the feudal moral standards.
