In the upper right corner is the "bright moon"
"when"
In the lower right corner are "You" and "Ba".
"When will there be a bright moon" comes from Su Shi's "Water Tune Song Tou", which is as follows:
When did the moon begin to appear? Ask heaven for wine. I don't know about palaces in the sky. What year is tonight? I'm willing to ride the wind to the sky, I'm afraid I can't stand the cold for nine days in a pavilion of fine jade. Dance to find out what shadows look like on the earth. The moon turned into a scarlet pavilion, hanging low on the carved window, shining on the sleepy self. The moon should not have any resentment against people. Why is it round when people are gone? People are sad and happy, and they are separated and reunited. The moon will darken or shine, and it will become round or round. Nothing is perfect, even in the past. I hope people will live for a long time and have a good scenery thousands of miles away.
