莫高窟第9窟的营建与晚唐归义军政权的政治背景密切相关,为学者所关注。根据窟内李氏家族供养人题记的情况,可证洞窟建成于李弘愿被清除之后、李弘定等人被杀之前。再结合张承奉称号的变化情况,可以确定该窟应建成于乾宁四年(897年)二月至光化元年(898年)之间。第9窟中张承奉所谓检校司徒及使相的称号均系其自称,而非索勋所授予。 The construction of Cave 9 at Mogao Grottoes is closely related to the political background of the Gui-Jun Regime in the late Tang Dynasty, which is of concern to scholars. According to cave inscriptions on the family dependents Li, permit cave built in Li Hong was willing to be cleared, before Li Hongding and others were killed. Combined with the change of the title of Zhang Chengfeng, we can confirm that the cave should be built between February and October of the fourth year of Ganning (897) and the first year of Guanghua (898). Zhang Cave in the ninth cave Zhang called the so-called school disciple and the title of the phase are their claim, rather than Suoxun granted.
