On February 22nd, 2008, accompanied by Mr Liu Fu, former director of Laishui Cultural Bureau, the research team visited Laishui Busan. Laishui Busan is located in Loucun Manchu Autonomous County, about 15 km northwest of the county seat, and is connected with Lingshan.

According to legend, the Yellow Emperor invented the boat here, and Linglun made musical instruments and twelve five-meter clocks here. Up to now, there are still legendary sites here, such as Leizu Cave, Huangdi Hidden Soldiers Cave, Lingquan (commonly known as Lingquan), Lingci Temple and Linglun Diaole Equality recorded in Baoding Fuzhi and Zhuozhou Zhizhi. Laishui has a world-famous intangible cultural heritage, which is the Gaoluo Concert. "Laishui Gaole" is said to be the ancestor worship music of Huangdi Temple created by Ling Lun. "Lai" means "sacrifice" in Shuo Wen Jie Zi. This ancient and profound musical repertoire has been stubbornly passed down by people in Laishui, Yixian and Xu Shui counties. Interestingly, in the Map of the Mountain and its tributaries, the ancient Laishui (now Juma River) flowing into the ancient Yellow River was originally called "Lunshui", which seems to be quite deep with the source of Linglun.

Laishui Busan, shaped like a kettle, is an ancient village. Because Busan is unique to modern county annals, it is speculated that the name of Loucun is earlier than Busan. It is also because of the invention of ships near the ancient Yellow River and the statement that Linglun's original music originated here, which has a historical and geographical basis that cannot be ignored.

At the foot of the mountain, the investigation team had a brief interview with Mr. Liu Fu-

(Liu Fu: According to the records of Laishui ancient county, when the Yellow Emperor fought Chiyou, he once hid soldiers in Busan, and more often he was the minister in charge of sacrifice, which is the place where he often lived-Linglun, the ancestor of China music. In the north of this mountain, there is a three-story cliff and half a slope. According to legend, it is the place where Linglun cast the bell, and now there is a lot of smelting metal waste residue in that place. An ancient pottery was unearthed at the top of Busan Mountain. There is a word on the pottery that no one can recognize at present. )
