The 300-word expansion of Early Spring is addressed to 18 members of the Ministry of Water Resources, including Zhang.

In early spring, it was drizzling on the streets of Chang 'an. This light rain, soft and delicate, like cream, quietly reminds people that spring is coming. When you look out to the suburbs, there are patches of new green everywhere between the hillside and Yuan Ye. From a distance, there seems to be a very light green, which is the grass color in early spring. Watching, people's hearts are suddenly filled with happy business. However, when you look closely with infinite joy, the color on the ground can't be seen clearly. Although the grass is turning green, it is still too small and tender.

This is the best time of the year in spring, far better than the late spring when the city is full of smoke and willow! Yes, early spring, this is the beginning of spring, from yellow to green, full of vitality. When can energy conservation arouse such great hope in people's hearts? Therefore, early spring is the best time of the year, just as early morning is the best time of the day, and childhood is the best time of my life.

This is a seven-character quatrain that describes and praises the beauty of early spring. The first sentence points out the light rain in early spring, and describes it as smooth and moist with "moist as crisp", which accurately captures its characteristics. The sentence is fresh and beautiful. There is also Du Fu's "Good rain knows the season, when spring comes." Sneaking into the night with the wind, moistening things silently "has the same effect."

The second sentence closely follows the first sentence, which describes the scenery after the rain. It's green from a distance, but it's not green from a close look. It depicts the hazy scene of grass soaking in rain in early spring. This can be compared with Wang Wei's "Fogs disappear when I enter them" and "Is the color of the mountain yes or no". Three or four sentences praise the scenery in early spring: "The most important thing is the benefits of spring, which is definitely better than tobacco willow." The light rain and grass color in early spring are the most beautiful things in the spring of a year, far exceeding the late spring scenery of the city of smoke and willow. Poetry about spring scenery, in Tang poetry, mostly takes beautiful late spring, but this poem takes early spring chant, thinking that early spring scenery is better than late spring, which is innovative.

In this poem, the poet only uses simple words to describe the unique scenery of early spring with common "light rain" and "grass color". Delicate descriptions, beautiful sentences and novel ideas give people a moist, comfortable and fresh aesthetic feeling in early spring.
