But the moon shines on the ditch,
Falling flowers deliberately drift with the tide,
Running water has no intention of falling flowers.
This poem comes from the brilliant story of pipa in Yuan Dynasty.
There are a few words in Yuan Gaoming's Pipa Story that exhort his father-"This tit is rude, but it will collide with my words. My words are not in the right place, son. My husband's words are contrary to my father's. I hate children's knowledge. I should have trusted the moon, but the moon shines on the ditch. "
