Autumn in the Three Gorges
Autumn has arrived in the Three Gorges. Autumn in the Three Gorges begins with orange pomelo trees on both sides. These trees grow on steep rocks and their leaves are as hard and straight as blue rocks. In autumn, they are black and green; And that heavy fruit, from green to yellow, gradually emerged from the middle of the leaves. At this time, they began to emit a fragrance, which filled the Three Gorges with mature autumn breath.
In the early morning, the transparent dew shines, and the gorge wind is a little cool, as if to sprinkle a layer of frost on the orange pomelo trees all over the mountains, fresh and clear; The sun came out, the dew disappeared, the orange pomelo trees were sunny and the green leaves were golden: it was another beautiful autumn in the Three Gorges.
At noon, the peaks were covered with golden armor, the sun jumped on the water, and the Yangtze River rolled like a golden python and screamed and washed away. It stirs up the brilliance of jumping and throws it on the steep cliffs on both sides. Therefore, the whole canyon is rippling and full of the warmth of autumn.
In the afternoon, the sun has not set outside the canyon, and a layer of blue fog has risen in the canyon. This makes the dusk in the canyon come early and go late. In the blue and transparent dusk, the reflections of cliffs on both sides of the river flock to the center of the river, leaving only a shining sky on the river, and the Yangtze River is like a bright stream.
Night has finally arrived. Fishing fires and lights are lit up one after another; Coupled with their red light reflected on the water, the Yangtze River seemed to blink and fall asleep. Only the barges that pass by occasionally, whistling, draw a shining road on the river; So the fishing fire and the bonfire, like waking up, swayed gently on the water.
Maybe it's because the mountains are too high, the valleys are too deep, the sky is too narrow, and the moon comes up late. At first, the canyon can only feel its hazy green light, which is connected with dusk; I don't know when it suddenly appeared on the mountain. Just like growing out of the mountain, it is a part of the mountain; Like a huge, smooth, shiny mica stone. At this time, the contrast between the shadow of the moon and the mountain is very obvious-the mountain is black as ink, standing on the wall, leaning towards the center of the river, as if it were going to fall down; And the moonlight, from the top of the mountain, along the deep, upright valley, poured green light straight to the river. Like a waterfall, flying down out of thin air; Like a plain brocade, hanging on the mountain.
This day is the Mid-Autumn Festival.
