This is what I found:

Historically, the Jade Emperor has frequently appeared in poetry articles, such as "Whose Jade Emperor flies into the spring breeze in Los Angeles in the dark", "The Jade Emperor makes Qiu Yun Yuan Ting, whose girl leans against the building to listen" and "Xuanzong Guifei plays the Jade Emperor and Yue Xian Ziyun Back". "The prostitute in Dunhuang is flying in the sky with the jade emperor in her arms." Wait, there are no examples here. In these allusions, is Yu Di just a description of the flute or does Yu Di really exist? Maybe no one has studied this problem yet! But at least it gives us a message: Why can't jade be used as a flute? ! Perhaps the ancients once thought about making flutes with jade, but due to the limitation of production tools at that time, it could not be completed, or it could be made, but it was too troublesome and difficult to popularize.

The origin of the jade emperor

Today, Yu Ling Yin Fei, the jade emperor of China, was born. After decades of research and experience accumulation by Mr. Huang, a folk artist, Yu Di, who originally only appeared in ancient poetry, really came to people's side. (Mr. Huang's resume: a national musical instrument producer, who was once a major member of Henan Musical Instrument Research Institute under the Henan Provincial Department of Culture, devoted his life to the research and production of musical instruments, including flute, flute, sheng, suona and erhu.
