"Learning without thinking is useless, thinking without learning is dangerous." This sentence tells us to handle the relationship between learning and thinking. Just studying and studying without learning to think will You will fall into confusion. The knowledge you have learned cannot be used in practice. No matter how many books you read, it will be in vain. Knowledge only acts as a two-legged bookcase. Thinking hard every day but refusing to lower your head to read is like water without a source or a tree without roots. It becomes a daydream and does not help others, oneself, or society.
