Emperor Zhaozong of Tang
At some point, then-reigning Emperor Zhaozong of Tang became aware of Xu Ji's reputation, and summoned him (probably to the capital Chang'an), wanting to meet him. When Xu arrived at the palace, however, Emperor Zhaozong was playing music with actors, and did not see Xu immediately. Xu was unimpressed, and, after meeting the emperor, requested to return to the mountains. He eventually took up residence at Jiangling. After the warlord Zhao Kuangming became the military governor ("Jiedushi") of Jingnan Circuit (荊南, headquartered at Jiangling), Zhao treated him with respect and often requested his advice on proper living.
