The Qingqiu Left Talent Charter is a deep interpretation of the Qingqiu Left Array Chapter by past generations, though the identity of the author remains unknown. As it is a hand-copied edition by Fox Er, there is even less to trace.
Given the characters 'Qingqiu', Lu Bei speculates that it most probably belonged to the secret techniques of the line of Fox spirits.
He's underestimating it, however. Apart from analyzing the Left Array Chapter, the entire text of Talent Charter also annotates techniques such as Philosophy of the Five Elements and the Eight Diagrams, covering a vast range of studies.
On the positive side, this is referred to as gathering all streams into the vast sea. On the negative side, it's indiscriminately eclectic - sliding over melon skin, writing about anything that comes to mind.
