《晋书·志·第六章》
国语》称，笙箫类乐器音律便于协和规范，这个说法是适宜的，也就是说它们易于运用变通的办法解决问题。角生变宫，姑洗生应钟。
《国语》曰，匏竹利制，议宜，谓便于事用从宜者也。角生变宫，姑洗生应钟也。
The "Guo Yu" states that the melody of sheng and xiao instruments is easy to harmonize and standardize, which is appropriate, meaning that it is easy to use flexible methods to solve problems. Jiao generates Bian Gong, Gu Xi generates Ying Zhong.
