"Learning is like sailing against the current. If you don't advance, you will retreat. " This sentence is a famous saying in Liang Qichao's Speech at the Welcome Meeting of Ticket Merchants in Shanxi in Qing Dynasty. This sentence uses a vivid metaphor to explain the importance of learning in a simple way, and encourages continuous efforts and progress in the process of learning.

This sentence also reflects the initiative and enthusiasm of learning. To sail against the current, you need to take the initiative to push hard and move forward actively. The same is true of learning. You need to actively learn new knowledge and skills and actively seek learning opportunities and resources in order to make continuous progress. Passive acceptance of knowledge, lack of active learning consciousness and action, can not make real progress.
