《史记·三十世家·赵世家》
他对大夫们说： 我到了天帝那里非常快乐，和百神在钧天游览。听到了宏伟的乐曲多次演奏，还看到了万舞，不像是夏、商、周三代的音乐，那乐声非常动人。
语大夫曰： 我之帝所甚乐，与百神游于钧天，广乐九奏万舞，不类三代之乐，其声动人心。
He said to the doctors: when I got to the God of Heaven, I was very happy, and I toured the Heaven with gods. Heard grand music played many times, and witnessed many dances, they differed from the music of the three dynasties of Xia, Shang, and Zhou, and the music was very moving.
