Appreciation of the ancient poem "Seven Wonders of the Equinox"?

The first sentence of the poem is about the vernal equinox, when the spring rain falls almost silently, which is similar to Du Fu's "moistening things silently". On the bank of the river, willows hang low and dance. There is a saying in the poem "Fishing Songs" written by Zhang, a poet in the Tang Dynasty, "There is no need to return to the oblique wind and drizzle". Xu Xuan obviously used this poem, but gave it new content.

It is said here that "Liu 'an sends guests home in an oblique wind", which means that Tomb-Sweeping Day will be in half a month after the vernal equinox. Wandering wanderers should go home to sweep graves and pay homage to their ancestors. In the past, I had to get home early because of inconvenient transportation and long journey. Therefore, the poet said here, let the spring breeze bring the homeless who live in other places home. Personification was used to make the poem lively at once.

This season in the north is a little late, and the climate is warmer than that in the south, but I don't know that the south is already the season when grass grows and warblers fly, everything recovers and spring warms bloom. It can be seen that China has a vast territory, and it is also a season, but it has completely different scenery. Although this poem "Vernal Equinox" has only four sentences, it describes the different scenery of the south of the Yangtze River and the north.

Extended data:

Xu Xuan was a writer and calligrapher in the Five Dynasties. He is a bachelor of Hanlin and a senior official. Later, Li Yu, the ruler of the late Southern Tang Dynasty, surrendered to Zhao Kuangyin, and Xu Xuan followed him as an official in the Great Song Dynasty. This official was a constant servant.

Xu Xuan once wrote three poems about the vernal equinox, in addition to this one, there are "Stealing Magnolia, Rain on the Vernal Equinox" and "Vernal Equinox Day". In the poet's works, the vernal equinox gives vivid images and becomes more vivid.
