Two editions name An Lushan's rebellion for this lot, while a variant title points instead to Fan Li sailing away on the lakes. An Lushan was a frontier general of Sogdian and Turkic descent who rose high in the favor of the Tang emperor Xuanzong and his consort Yang Guifei, then fell out with her cousin, the chief minister Yang Guozhong. In 755 he rebelled, took Luoyang, broke through Tong Pass and drove the emperor to flee to Sichuan. He declared his own dynasty and was murdered by his own son within two years. The poem's warning not to chase the scent of flowers in the woods is the point: a man with helpers and a clear channel left it for a prize he could not hold. The middle grade holds both sides, steady progress for the patient and ruin for the reckless.
