In the past, the sea was hardly water. It means that people who have seen the magnificent sea can no longer weigh the water elsewhere. Only Wushan cloud can be called a real cloud.

Once I tasted the vast sea, I felt that the water in other places was pale; Once you have experienced the clouds in Wushan, you feel that the clouds elsewhere are eclipsed. It means that people who have seen the magnificent sea can no longer call the water in other places water. Only Wushan Cloud can be called a real cloud.

The original poem uses the water of the sea and the cloud of Wushan as a metaphor for first love. Except for the first love that the poet has read, thought and loved, he will never be moved by other women again.

To eliminate suffering, break it first. Only by not being stubborn in pursuit and not aiming at strength can the mind be freed from worries and burdens and be free.
