A teacher in Shanghai played a homemade guzheng with a cardboard box rubber band. What do you think of this teacher's playing?

I think this teacher plays very well. She is also very creative and talented. She can make a guzheng out of cardboard boxes and rubber bands and play a song. Very impressive. The Lonely Brave, which she played with her homemade guzheng, is also very nice. This teacher is very good. It is not easy to make a zither by herself, and she can make the timbre of her own zither similar to that of a zither, and the sound she plays is amazing. Because of the recent serious epidemic in Shanghai, many people are isolated at home, and the teacher is also isolated at home, but because she has nothing to do, she thinks about whether she can make a guzheng herself. Then the teacher found a paper box, a pen and some rubber bands, and it was done. She fixed the pen on the paper box and then tied a rubber band. By adjusting the tightness of the rubber band, the rubber band makes different sounds. Finally, after debugging, the teacher made his own guzheng, and also played a paragraph and uploaded it to the short video platform. Her performance of "The Lonely Brave" was particularly beautiful. Because she is a guzheng teacher and knows guzheng very well, she can make a simple guzheng from a few very ordinary and simple items so that she can play it alone to kill time. Although it's not a real guzheng, the voice played by this guzheng teacher is similar to that of a guzheng. This teacher plays really well and has good intonation. Although it is not a regular guzheng, it is not easy for a simple guzheng to play so well. This teacher is still very talented. It is remarkable that he can make a simple guzheng through his skillful hands. Moreover, he can also play sounds with this simple guzheng, which is even more remarkable. I admire this teacher for coming up with this idea to play the guzheng.
