In Xu Zhimo's famous essay "Cambridge as I Know It", there is a paragraph describing Cambridge and its upstream and downstream scenery. What are the words?

The spirituality of Cambridge lies in a river; I dare say that He Kang is the most beautiful water in the world. The name of this river is Granta, and the name of Rivergamm. There may be a difference between bunk beds, but I'm not sure. The river twists and turns. Upstream is the famous Byron Pool, where Byron once played. There is an old village called Gransted, and there is an orchard. You can drink tea in the shade of many peaches and plums. Flowers and fruits will fall into your teacup, and little birds will peck at your table. This is a world of difference. This is upstream; Downstream comes down from chesterton, and the river spreads out, which is the place for boating competitions in spring and summer. There is a dam at the boundary between upstream and downstream, and the water is very urgent. Listening to the sound of water under the starlight, listening to the bells near the village, and listening to the sounds of tired cattle and grass by the river are the most mysterious species in my Cambridge experience: the beauty and tranquility of nature, tuned in the tacit understanding of starlight and waves, accidentally drowned your soul. But the essence of He Kang lies in its middle strength, the famous "back", which is the building of several most famous colleges on both sides. From top to bottom, pembroke, St. Catherine, King, Claire, Trinity and St. John. The most unforgettable passage is the junction of Calea and Wang's Academy, and the beauty of Calea is close to the majesty of Wang's Chapel. There are more beautiful and solemn buildings in other places, such as the Louvre on the Seine in Paris, the banks of Rialdo Bridge in Venice, and the emerald-colored Cui Weiwei Bridge. However, the "back" of Cambridge has its particularity, which cannot be easily summarized in one or two sentences. Its artistic conception is beautiful and elegant, which can be said to be beyond painting and lively music. Nothing is more harmonious and symmetrical than this group of buildings! On painting, only Connor's field can be compared; On music, only Chopin's Serenade can match it. Even this can't give you a vague impression. The beauty it gives you is simply a kind of spirituality. If you stand in the shade of the big citrus reticulata tree next to the Wangs College and look out, on the right, across a large shallow lawn, is our alumni residence (fraternity), which is not too early, but its charm is undeniable. Its pale stone wall is full of colorful roses swaying in the spring and summer breeze, and the church moves to the left, and the forest-like pavilion always points to the sky; On the left is Calea, ah! That incredibly exquisite square, who said that this is not the incarnation of St. Caria, and that stone does not shine with her holy spirit? On the back of Calea, the most expensive and luxurious Trinity College in Cambridge, an amazing Byron statue sits on the library building by the river. But at this moment, your attention has already been captured by Calea's three-ring tunnel bridge like magic. Have you ever seen Xiqiao Broken Bridge on the Bai Causeway of West Lake? (It's a pity that they have long been leveled by the automobile company that represents the ugly spirit of modern times, and now they have left this world forever with the desolate Lei Feng. You can't forget the mottled moss on the bridge, the antique wooden fence and the lakes and mountains leaking under the arch of the bridge, can you? Calea doesn't have such a decent canopy, and it's no better than Guanyin Bridge next to Louxian Temple in Lushan Mountain, with a bird's eye view of the Five Old Qifeng and a deep pool waterfall under it. It's just a small bridge with a three-ring hole, and the mouth of the bridge is only covered with fine waves and swaying shadows. Rows of small white stone balls on the bridge are just exaggerated decorations such as herbs and wild flowers on the head of the village girl. But you look intently, more intently, and then you reflect on your state of mind to see if there is any vulgar thought. As long as your aesthetic instinct is immortal, this is your chance to realize pure beauty and magic! But you still have to choose the time to enjoy it. The weather and climate in Britain are extremely bad. Winter is ridiculously bad. When it is foggy and blind, you must be willing to go to hell itself without hesitation. Spring (there is almost no summer in Britain) is even more ridiculous and lovely, especially in the most gradual and gorgeous dusk in April and May, which is really gold. A night by the He Kang River is a tonic for the soul. Ah! At that time, I was very sweet, alone, very sweet and carefree. Night after night, I saw myself leaning against the railing of the bridge and staring at the western sky:-Look at the quiet shadow of the bridge and count the ripples of mother-of-pearl: I leaned against the moss of the stone railing, and the moss cooled my heart; ..... There are several complicated scenes as delicate as gossamer: unforgettable July dusk, the trees in the distance are very quiet, like a mountain shape splashed with ink, lined with soft colors, and the wonderful meaning can only be captured at the edge of Qiu Meng; . .....
