Appreciation: This couplet's "Widening at Low Tide" and "Broadness" are the result of "Tidal Flat". The spring tide is surging and the river is vast. Looking around, the river seems to be flat with the shore, which broadens the horizons of the people on board. This sentence is very grand, and the next sentence "No wind stirs my lonely sail" is even more exciting. "Hanging" means hanging straight from one end to the other. The poet uses "the wind is right" instead of "smooth sailing" because "smooth sailing" alone is not enough to ensure "sailing" Although the wind was smooth, it was strong and the sails bulged into an arc. Only under the condition of downwind and breeze can the sail be "hung". The word "positive" includes both "shun" and "harmony".
These necklaces are: ... night gives way to the ocean of the sun, and the old year melts in freshness.
Appreciation: when the night has not subsided, a red sun has risen from the sea; The old year has not passed, and the river has shown spring. "Day after day" and "spring into the old year" both indicate the alternation of time series, and they are in such a hurry. These two sentences are also very kung fu. The author regards "the sun" and "spring" as symbols of new beautiful things from the perspective of refinement, emphasizes them by mentioning the position of the subject, personifies them with words such as "life" and "ru", and endows them with human will and emotion.
