This organ is of the “Ming Feng” (Singing Phoenix) brand, manufactured in Shanghai , probably in the 1930s. It can produce a flute-like sound if one of the four knobs is pulled out. The organ has a built-in chair which can be pulled out as shown in this picture. This piece of instrument is currently displayed at “Old Shanghai Tea House” in the old shopping area called Lao Chenghuan Temple in Shanghai.
This picture circa 1920 shows a primary school, the pioneering Xueqian School in Changshu, music class in session. An organ is used to accompany the singing by the pupils.
