Seeking documents: appreciation of poetry, what method was used in the first connection between Taoism and enthalpy, and what kind of picture was depicted. This poem expresses.

Tao is matter.

Huanggongdu

The flowers are gone, the warbler is old, the mulberry leaves are thinning, and the silkworm is sleepy.

Semi-wet and semi-sunny plum rain, autumn cold and warm wheat.

Who can choose to sell wine in the village and write poems on the postal wall is accidental.

There is nothing wrong with the square inch, and it is rough and delicious.

Explanation:

The first couplet and parallel couplet adopt the methods of duality and parallelism. The season described is probably late spring and early summer, and the leaves of konoha will be very thin, alternating cold and warm. The author's mood at this time is as boring as the weather. In spring and summer, the weather is changeable, alternating cold and warm, which makes people feel sad most easily. If the author lived in that turbulent era as the background, the luck of the Qing court, like the scene at this time, was exhausted and lost everywhere.

It is not surprising that the author sees this lifeless and boring scene and the feelings revealed in the poem. This poem can be said to convey a sense of boredom with poetry imperceptibly.
