Hvem daterte 虢國夫人?

Det var også andre keisere med navnet Xuanzong

Keiser Xuanzong av Tang (kinesisk: 玄宗, født som Li Longji den 8. september 685 i Luoyang i Kina, død 3. mai 762) var keiser under Tang-dynastiet i Kina, fra 712 til 755.

Qingming ble gjort til fest (Qingmingfesten) under keiser Xuanzong i 732. Det sies at utgangspunktet var at de rike hadde utviklet det som keiseren mente var et alt for høyt antall kostbare og intrikate seremonier knyttet til forfedrekulten, og han anså at det var på en plass med en forenkling. Han forordnet at de formelle andaktsøvelser knyttet til slektens avdøde forfedre ved de avdødes graver kun skulle finne sted ved Qingming.

Hans keisertid er inndelt i tre herskeræraer: Xiantianæraen (712–713), Kaiyuanæraen (713–741) og Tianbaoæraen (742–756).

Yang Guozhong (traditional Chinese: 楊國忠; simplified Chinese: 杨国忠; pinyin: Yáng Guózhōng; Wade–Giles: Yang Kuochung) (died July 15, 756), né Yang Zhao (楊釗), was a Chinese politician who served as principal chancellor of the Tang dynasty from 752 to 756, late in the reign of Emperor Xuanzong. Known in his youth as a gambler and wastrel, Yang rose rapidly to political power after his distant cousin, Yang Yuhuan, became Emperor Xuanzong's favorite consort in 744. His familial ties and skills as a financial administrator helped him navigate the tumultuous court politics of the late 740s and early 750s to become the emperor's leading chancellor in 752. While Yang enjoyed Emperor Xuanzong's trust, his competence as chancellor was questioned and he became entangled in a fierce rivalry with an erstwhile political ally, the general and imperial favorite An Lushan. Yang was blamed for precipitating An's cataclysmic rebellion in 755. In the following year, he forced the Tang army of Geshu Han, then holding favorable defensive positions in Tong Pass, to confront the rebel army, leading to a rout of Tang forces and the fall of the imperial capital, Chang'an. Yang attempted to flee to his base in Chengdu with Emperor Xuanzong, but when the imperial party stopped at Mawei Station in modern Shaanxi, Yang and his family, including Yang Yuhuan, were massacred by imperial guard soldiers who blamed them for the chaos.
