Watching the pair of geese go south in autumn, the autumn wind is bleak and their old friends are gone. When I was alone by the river watching the river flow away, I couldn't help feeling sad and lonely. A group of fair-weather friends can help their career prosper, and old friends will eventually meet. These are old friends. Yuanyang plays in the water, seagulls fly around, with lovers, don't doubt your feelings for them. Osmanthus flowers bloom in the courtyards on both sides, and the orchard bears fruit in autumn. Do more good deeds when you are young, so as not to be lonely in your later years. I don't want to lust after wine and color, all because of previous lessons.
