What does the man mean when he says that it was once difficult for the sea to touch water?

A man says that the sea is difficult for water, which shows his love for women, his unswerving feelings for women, and his loyalty to love. 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. This is a poem in Yuan Zhen's Five Thoughts.

Similar to the poem that once the sea was difficult for water.

When all the mountains are leveled, the sky and the earth merge, and only then will I leave you. I want to know you and live a long life. It was a long time ago that I met her, but since we separated, the time has become longer. The east wind is blowing, the flowers are dying, and the silkworms in spring will weave until they die, and this endless sadness will continue forever.

The earth endures, and the sky endures; One day both will end, and this endless sadness will last forever. A moment that should last forever has come and gone before I know it. Without Cai Feng's wings, it is impossible to be Qi Fei in fly with me; The heart is like a soul, and the feelings are the same. If it works, why not die? I would rather be a mandarin duck than a fairy.

The ends of the earth are poor and white, only endless lovesickness. I don't regret that my belt is getting wider and wider, which makes people haggard for Iraq. Ah, there is love in life, and love is in the depths of madness. This is not irrelevant to hate-the wind overhead, the moon in the sky. The candle on the table lit the heart, and it also saw the parting; You see, it shed tears for us and flowed to the morning.
