I have a piano by Nie Er. Few people know now. /kloc-0 was produced by Shanghai Piano Factory in/987, and was discontinued in 1989. I worked in Shanghai Piano Factory during my menstrual period and bought tickets at that time. During my period, my master asked me to pick out this piano one by one from hundreds of nieer ears. This piano of my age is now over 30 years old. I can't play the piano myself. Many small parts are damaged because I don't play for a long time.
