Emperor Gaozong of Tang
Emperor Gaozong of Tang (21 July 628 – 27 December 683), personal name Li Zhi, was the third emperor of the Tang dynasty in China, ruling from 649 to 683 (although after January 665 power and governance was primarily in the hands of his powerful second wife Empress Wu, later known as Wu Zetian).
Emperor Gaozong was the son of Emperor Taizong and Empress Zhangsun.
Emperor Gaozong was aided in his rule by Empress Wu during the later years of his reign after a series of strokes left him incapacitated.
Emperor Gaozong delegated all matters of state to his Strong wife and after he died in 683, power fell completely into the hands of Empress Wu, who subsequently became the only Empress regnant in Chinese history.
After his death, he was interred at the Qianling Mausoleum along with Wu Zetian.
Historians have generally viewed Emperor Gaozong as a weak ruler, inattentive to the business of the state and leaving such business to his powerful wife Empress Wu.
During the first part of his reign, Tang territorial gains, which started with his father Emperor Taizong, continued, including the conquest of Baekje, Goguryeo, and the Western Turkic Khaganate, but throughout the 670s, much of those gains were lost to the Tibetan Empire, Silla, Khitan, and Balhae.
Further, territory previously conquered that belonged to both the Göktürks and the Western Turkic Khaganate were subjected to repeated rebellions.

Emperor Ruizong of Tang
Emperor Ruizong of Tang (22 June 662 – 13 July 716), personal name Li Dan, also known at times during his life as Li Xulun, Li Lun, Wu Lun, and Wu Dan, was the fifth and ninth emperor of Tang Dynasty.
He was the eighth son of Emperor Gaozong and the fourth son of Emperor Gaozong's second wife Empress Wu
(During the first period, he did not rule the, and the entire government
In the hands of to his mother, Empress Wu, later as Wu Zetian Is known Was).
In February 684, Li Dan's mother Empress Wu demoted his older brother Emperor Zhongzong
(Li Xian) who had attempted to rule free of his mother, and named him emperor (as Emperor Ruizong).
Emperor Ruizong, however, was a puppet under control of his mother and did not have any real power.
In October 690 he ceded the imperial throne to his mother, who installed herself as empress regnant – the only woman in Chinese history ever to rule as empress regnant.
Emperor Ruizong was reduced to the position of crown prince, with the unconventional title of "Huangsi" (皇嗣, "imperial successor").
In the following years, Empress Wu's nephews Wu Chengsi and Wu Sansi tried to have one of them named heir to the throne, but Wu Zetian resisted these calls.
Eventually, in October 698, faced with foreign invasion and dissatisfaction at home, Empress Wu accepted the suggestion of the chancellor Di Renjie and recalled the exiled Li Xian to the capital Luoyang.
Soon, Li Dan offered to yield the position of crown prince to his elder brother, and Li Xian became crown prince instead.
In 705, a coup overthrew Wu Zetian and restored Emperor Zhongzong to the throne.
The five years of Emperor Zhongzong's reign were dominated by Zhongzong's empress consort, Empress Wei.
In the beginning of July 710, Emperor Zhongzong died, allegedly poisoned by Empress Wei who then named Zhongzong's youngest son Li Chongmao the Prince of Wen emperor (as Emperor Shang).
A mere two weeks later, Li Dan's sister Princess Taiping and Li Dan's son Li Longji
the Prince of Linzi launched a coup which resulted in the death of Empress Wei.
Princess Taiping, Li Longji, and Li Longji's brother Li Chengqi
the Prince of Song then persuaded Li Dan to take the throne himself, and he agreed, returning to the throne in Emperor Shang's stead.
Li Longji, although not the oldest son, was made crown prince on account of his accomplishments.
Soon, however, tensions between Princess Taiping, who had many supporters, and Li Longji mounted.
Eventually, in September 712, Emperor Ruizong, believing that astrological signs called for a change of emperors, abdicated in favor of Li Longji (as Emperor Xuanzong).
However, at Princess Taiping's suggestion, Emperor Ruizong, now carrying the title of "Taishang Huang" (retired emperor), continued to wield actual power.
However, in 713, suspecting Princess Taiping of planning a coup, Emperor Xuanzong acted first, killing her associates and forcing her to commit suicide.
After the death of Princess Taiping, Emperor Ruizong himself yielded imperial powers to Emperor Xuanzong and left the governmental scene.
He died in 716.

Guo Daiju
Guo Daiju( 郭待舉) was an official of the Chinese dynasty Tang Dynasty, serving as a chancellor during the reign of Emperor Gaozong as well as the regency of Emperor Gaozong's wife Empress Wu( later known as Wu Zetian) over their sons Emperor Zhongzong and Emperor Ruizong.
Despite Guo's high status, little is firmly established about his background or career except for the years that he served as chancellor—as, unusual for a chancellor, he did not have a biography in either the" Old Book of Tang" or the" New Book of Tang".
He was from Yingchuan( 潁川, in modern Xuchang, Henan.)
According to the table of chancellors in the" New Book of Tang", his father was Guo Chufan( 郭處範), who at one point served as the secretary general of Zhucheng County( 諸城, in modern Weifang, Shandong).
As of 682, late in the reign of Emperor Gaozong, Guo was" Huangmen Shilang"( 黃門侍郎), the deputy head of the examination bureau of government( 門下省," Menxia Sheng"), when he was given the designation" Tong Zhongshu Menxia Pingchangshi"( 同中書門下平章事), making him a chancellor" de facto".
However, nothing was recorded about his acts as chancellor, and the next reference to him was in 684, by which time Emperor Gaozong had died and been succeeded by his son Emperor Zhongzong — who was then deposed by Empress Wu, then empress dowager and regent, for disobeying her—and then by Emperor Zhongzong's brother Emperor Ruizong.
In 684, there had been a rebellion by Li Jingye the Duke of Ying against Empress Dowager Wu's rule, and while Li Jingye's rebellion was quickly defeated, the chancellor Pei Yan was executed on suspicion that he sympathized with Li Jingye's rebellion.
After Pei's death, there were a series of official movements involving officials who had tried to defend Pei, and as part of these movements, Guo was stripped of his status as chancellor and made a member of the staff of Emperor Ruizong's crown prince Li Chengqi, but just a month later, he was further demoted to the post of prefect of Yue Prefecture( 岳州, roughly modern Yueyang, Henan).
Nothing further about him was recorded in history, although the table of chancellors in the" New Book of Tang" indicated his grandsons Guo Run( 郭潤) and Guo Na( 郭納) later served as imperial officials.
