What kind of feelings does the poem "Days when the wind is light and the clouds are light" express about the sea?

Qiantang (now Hangzhou, Zhejiang) has been a famous big city in history since the Tang Dynasty, and it developed further in the Song Dynasty. Liu Yong has lived in Hangzhou for a period of time and has personal experience and deep feelings for the scenic spots, customs and customs of Hangzhou. Therefore, in this poem, he can describe Hangzhou with vivid pen and ink. The beautiful scenery of the West Lake, the spectacular scenery of Qian Jiangchao, the prosperity of downtown Hangzhou, the enjoyment of the local upper class and the working life of the lower class have all been written by the poet and painted into a beautiful, magnificent and vivid picture. The value of this painting is not only that it depicts the beautiful mountains and rivers in Hangzhou, but more importantly, it shows the local customs at that time. "The southeast shape wins, and the three Wu cities will be generals", and the pen is broad and straight up and down. Two four-character antithesis, great momentum and extraordinary strength. "Southeast", in terms of direction; "Three Wu", in terms of geographical location. Explain the vast geographical space and vast territory, give people a sense of openness and arouse people's reading expectations: where did it occupy the right position at the right time? The next sentence is followed by an answer: "Qiantang has been prosperous since ancient times." "Since ancient times" has highlighted the long history and prosperity of Hangzhou. Next, the poets counted the natural scenery and human landscape of Hangzhou one by one. The following three sentences give a vivid explanation of "metropolis", "material victory" and "prosperity" in the first sentence respectively. "Smoke willow painting bridge, wind curtain and green curtain, the number of 100,000 people is staggering." Looking from a distance, weeping willows contain smoke, mist is like gauze, and Hongqiao is picturesque. It's really a beautiful scenery that only exists in paintings. This place is full of people, all kinds of buildings, all terrain, row upon row, eaves teeth scattered all over the floor; Take a closer look, the breeze blows, and the curtains of thousands of families sway gently, which seems to be refreshing. This is really a "metropolis" scene. "Uneven" describes the uneven height of pavilions, while "100,000" refers to a large population, which is not necessarily an exact number. "Clouds and trees surround the dike sand, and the waves roll with frost and snow, and the natural hazards are endless." The line of sight turned from the city to write "Sheng Xing" on the Qiantang River. Towering ancient trees surround the riverbank, and the surging river waves are rushing like anger, stirring up white waves like frost and snow. The magnificent Qiantang River is like a natural trench, which blocks the invasion of the enemy in the north. The word "winding" indicates that ancient trees are in rows, long dikes are winding, and the word "rolling" is like a raging wave. "Pearl in the city, Luo Qi in every household, competing for luxury." Zoom in and walk around the market. Beads, jade and precious stones are all over the city, and every household has beautiful cabinets. People's clothes are glamorous and luxurious, and they compete with each other. "Pillar", "profit" and "struggle" have put economic prosperity and rich and luxurious life into practice. The beauty of Hangzhou lies in the West Lake, and the beauty of the West Lake lies in the beauty of scenery and people. "The heavy lake is stacked in Ting Anne, with Sanqiu cinnamon and Shili lotus." There is a lake outside the lake and a mountain outside the mountain. The mountains and waters of the West Lake are beautiful, really beautiful. Even more beautiful is "Sanqiu Guizi, Shili Lotus", a timeless quatrain. "Sanqiu" means that osmanthus fragrans has a long flowering period and a strong fragrance, which will last for a long time; "Shili" means that lotus flowers are widely planted in the lake. When it blooms, it can be said that "the lotus leaves are infinitely blue the next day, and the lotus flowers are of different colors". One sentence brings out many images, such as lakes, mountains, autumn moon, sweet-scented osmanthus and lotus flowers, which makes people relaxed and happy. "Sanqiu Devil" reminds people of the beautiful legend about the West Lake. Legend has it that every Mid-Autumn Festival in Lingyin Temple and Tianzhu Temple in West Lake, dew cinnamon often falls from the sky, which is very fragrant. It fell from the osmanthus tree in the Moon Palace and was given by the lonely Chang 'e, so Song wrote in Lingyin Temple: "The laurel tree falls in the moonlight, and the fragrance is floating outside." Bai Juyi's "Recalling Jiangnan" also includes "Looking for Guizi in the Temple under the Moon". Beautiful legends add a mysterious and ethereal color to the beautiful West Lake. The two sentences of "Clear the sky with strong management, and let Brother Ling drown the night" are intertextual, that is, clear the sky with strong management, drown the night, and let Brother Ling drown the night and clear up. It means that the flute is singing day and night, flying in the clear sky and rippling in the moonlight. "Get" makes the piper and driller's natural and cheerful feelings increase sharply; Disc shows people playing the flute in the lake, and the flute song seems to ripple with the lake, showing a light and pleasant appearance. "Playing to catch lotus dolls", the old people fishing by the lake are at ease, and the children picking lotus in the lake are noisy and playful. In a word, we show a picture of the happiness of the people in peace and prosperity. "A thousand riding high teeth, drunk listening to flutes and drums, enjoying the haze." Dignitaries travel with dignity and prestige, and they really have the potential to respond with one voice and one voice. In my spare time, I like wine tasting, poetry painting and landscape appreciation. "The map of the future will be good, and I will go back to Fengchi to boast." At this point, it shows that the purpose of writing is to pay homage to Sun He. "One day" and "returning to Fengchi" are good wishes for Sun He's career prospects. This "beautiful sight" is enough to "boast" the people of the imperial court, and then it comes down to praise the magnificent Hangzhou.
