How Many Years Has the Country Been?

I saw the world in the mortal world, but it was just a few years of ups and downs; the new scarlet yarn covered the old dreams in the dust, and the young woman fell in love with the young man. I looked at the world in the mortal world. The characters and right and wrong flowed through the years; the waves behind them embraced the waves in front, and the good wine of the day overwhelmed the suaveness of the day. Sometimes the moon is bright, and sometimes the flowers are yellow. I look back at the mountains and rivers in the mortal world, where the dim lights are dimming, the scenery how many years ago, how it will look after so many years. Conception:
