In ancient China, there was a piano-making technician named Qiaozhi. Once, he got a piece of sycamore with good quality. He carefully made a piano out of this piece of wood. After winding it, the pop-up piano tinkled, like flowing clouds and water, like a golden jade impact, which was very beautiful. The workers' overseas Chinese thought it was the best piano in the world, so they dedicated it to the music official of the imperial court. The music official asked the musicians to identify the piano. When the musicians saw it, they all shook their heads like rattles and said, "This piano is not an guqin!" " I returned the piano to the overseas Chinese of workers.

The second overseas Chinese, who didn't know

about the work, came home and asked the painter to draw a series of broken lines on the piano, and asked the calligrapher to carve ancient characters on the piano. Then, he packed it in a box and buried it in the soil. A year later, the workers' overseas Chinese dug the piano out of the ground. When I opened the lid of the box, I saw that Qin was covered with moss and pieces of mildew. Overseas Chinese workers took this piano to the market to sell. A rich man bought the piano at a high price and presented it as a treasure to the music official of the imperial court. When the musicians opened the piano case, they all nodded like chickens pecking rice, and repeatedly praised: "Good piano, good piano, this is an authentic ancient piano, which is really a rare treasure in the world!"
