《瑞鹤仙·四山秋气爽》是元代作家元好问创作的一首诗词。以下是对这首诗词的中文译文、诗意和赏析：
四山秋气爽，
The autumn air is refreshing in the four mountains,
正云淡、银河露零仙掌。
The clouds are light, and the Milky Way reveals the palm of a celestial being.
轻烟瑞屏嶂。
Light smoke veils the majestic peaks.
有文星一点，
There is a shining literary star,
□从天上。
□(此处缺失) from the heavens.
襟怀倜傥。
Broad-minded and extraordinary.
笑谈间、光焰万丈。
Amidst laughter and conversation, brilliance shines infinitely.
向玉皇，
Facing the Jade Emperor,
案底秋毫□纸，
On the desk, a single autumn hair writes on the paper.
屡承天奖。
Repeatedly receiving heavenly rewards.
何况云龙风虎，
Not to mention the mighty dragons and tigers,
万乘故人，两朝耆望。
Old friends from thousands of chariots, respected in two dynasties.
油幢玉帐。
Oil lamps and jade curtains.
听环佩，丁东响。
Listening to the sound of tinkling ornaments, the melody resounds.
有弹弦吹竹，
There are plucked strings and bamboo flutes,
年年高会，增壮中秋气象。
Year after year, the grand gathering enhances the atmosphere of the Mid-Autumn Festival.
□月中玉兔长生，
In the moon, the Jade Rabbit lives long,
借公醉赏。
Borrowing the public's intoxication to appreciate.
