The text is:
Line on the right: Still planting grass? A busy place (incomplete words)
Line on the left: Where? How many words can there be in time (incomplete)
The content comes from Qin Shaoyou's poem "Butterfly Loves Flowers": the bell sends the chicken to announce the dawn at dusk, and the twilight urges each other. When is the world? People will get old through the ages, and the grass will grow in spring. There are many people in busy places, but few places for leisure. How many people can understand leisure time? Alone in a small building, the world is a little small.
I looked it up and found the original.
The original calligraphy is from Zhang Bi's works in Ming Dynasty. (The first sentence reads: The bell at dusk sends the chicken until dawn)
