What do you mean by green hills on the rainy shore?
"Green hills on both sides of the strait are opposite", which is a positive description of Tianmen Mountain. The word "opposite" points out the relationship between Tianmen Mountain and the Yangtze River. The word "opposite" just shows the majestic posture of Tianmen Mountain standing across the river. The cliff is steep and opposite to the door, giving people a sense of sublimity that they can only look up. The word "Chu" is superb and refined.
