Autumn in the Three Gorges

It is already autumn in the Three Gorges. Autumn in the Three Gorges begins with the orange and grapefruit trees on both sides of the river. These trees grow on steep rocks, and their leaves are as hard and straight as the blue rocks. In autumn, they are so green that they turn black; and the numerous fruits turn from green to yellow, gradually emerging from the middle of the leaves. At this time, they began to emit a fragrance, filling the Three Gorges with the atmosphere of mature autumn.

In the morning, the transparent dew is shining, and the gorge wind is a little cool, as if a layer of white frost has been sprinkled on the orange and grapefruit trees all over the mountain, fresh and clear; when the sun comes out, the dew disappears, and the orange and grapefruit trees are shining. Under the sunshine, the green leaves are golden: the Three Gorges is once again a bright autumn.

At noon, the peaks are covered with golden armor, the sun is jumping on the water, and the Yangtze River is like a golden-scaled python, rolling, roaring, and flowing.

Its surging, jumping brilliance is projected onto the steep cliffs on both sides. As a result, the entire canyon was filled with ripples of light and the warm atmosphere of autumn.

In the afternoon, the sun has not yet set outside the gorge, and a layer of cyan fog has already risen in the gorge. This makes dusk in the gorge come very early and go very late. In the blue and transparent dusk, the reflections of the cliffs on both sides of the river swarmed towards the center of the river, leaving only a ray of luminous sky on the river surface, and the Yangtze River was like a bright stream.

Night finally came. The fishing fires and beacons light up one after another; together with the red halo they reflect on the water, the Yangtze River seems to be blinking and sleeping. Only the occasional barges passing by on their way blew their whistles and carved a luminous path on the river; then the fishing lights and beacons swayed gently on the water as if they were awakened.

Perhaps because the mountains here are too high, the canyons are too deep, and the sky is too narrow, the moon rises very late. At first, I could only feel its hazy green light in the gorge, connected with the dusk; but at some point, it suddenly appeared on the mountain. Like it grew out of the mountain and was part of the mountain; like a huge, polished, shiny mica stone. At this time, the contrast between the moon and the shadow of the mountain was extremely obvious - the mountain was as black as ink, standing steeply, leaning towards the center of the river, as if it was about to fall down; while the moonlight, from the top of the mountain, followed the deep, upright path. The ravines of the valley cast green light straight onto the river. Like waterfalls flying down out of thin air; like pieces of brocade hanging from the mountain.

This day is the Mid-Autumn Festival.
