What does it mean that "the early summer is still peaceful and the grass has not rested"?

It means that in early summer, the weather is finally refreshing and warm, and the grass has never withered because of the arrogance of the sun.

From the Southern Song Dynasty poet Xie Lingyun's five-character ancient poem "Swim the Redstone into the Sailing Sea". This poem is full of language, elegant but not artful. The perfect combination of emotion, scenery and reason makes it a masterpiece of landscape poetry.

The whole poem (excerpt) is as follows:

The first summer was peaceful, and the grass didn't rest. Water stays in the morning and evening, and the clouds are repeated.

Zhou Lan is very tired, but Kuang is very poor. There is steady flow after Sichuan, but Jason Wu does not send it.

The translation is as follows:

Early summer is still fresh and warm, the grass has not stopped growing, and it is still a thriving scene. The boats on the water are connected with the morning and evening, and they can't tell the morning and evening. Clouds and rosy clouds change many times, sometimes cloudy, sometimes full of rosy clouds.

I'm tired of seeing the seaside scenery, let alone looking around. The wave god lets the river flow quietly, but Uncle Shui doesn't make waves.

Extended data:

The sentence "Keeping Summer" echoes the poem "I am tireless in youth, I have seen Zhu Ming move" in You Nan Ting, which not only points out the holiday season, but also shows a complex mood that cannot be comforted.

You Nan Pavilion was moved by the scenery. Judging from the iteration of spring and summer, it is deeply sad that the prime of life has gone and he is sick in Sri Lanka. What is said here is that it is early summer, the weather is finally refreshing and warm, and the grass has not withered because of the arrogance of the sun. It can be seen that the poet seems to have recovered slightly from the sadness of his previous poems.

In particular, we can notice that "the fragrant grass is still in its infancy", in fact, the reverse is "Li Sao" and "I am still in infancy before I am old, and I am afraid that the thrush will sing first, making my husband's grass not fragrant". Then, in "Masturbation", we can see Xie Ke's arrogant character of "courting officials".

However, this relief can't last long. It's monotonous to swim around the red stone dozens of miles to the south outside the county, and the change of rain or shine and the appearance of clouds have lost their freshness because of frequent appearance. This trip to the seaside has been exhausting, and more importantly, they are faced with a barren land in the far north and a poorer and northerner sea.

Some people think that "Kuang Nai-poor" is a poet who is full of lofty sentiments and bent on going to sea. But the word "Kuang Nai" clearly means "tired". Before seeing the sail sea, the poet was in a bad mood.
