Li Chengqian
Li Chéngqián (李承乾) (618 – 4 January 645), courtesy name
Gaoming (高明)
, formally Prince Min of Hengshan (恆山愍王), was a crown prince of the Chinese Tang Dynasty.
He was Emperor Taizong's oldest son and first crown prince, but was replaced later by his younger brother Li Zhi (the eventual Emperor Gaozong).
Li Chengqian was created crown prince in 627 at the age of eight, after his father became emperor in 626.
In his youth, he had a reputation for good judgment, but was also said to be suffering from a foot illness.
Later on, he was said to be frivolous, favoring Tujue customs instead of studying about ways to rule an empire.
He lost favor in Emperor Taizong's eyes to a younger brother, Li Tai the Prince of Wei.
(Both were born of Emperor Taizong's wife Empress Zhangsun.)
In 643, in fear that Emperor Taizong was about to depose him in favor of Li Tai, he plotted with the general Hou Junji to overthrow Emperor Taizong.
The plot was discovered, and he was deposed and reduced to commoner rank, but Emperor Taizong, believing that Li Tai to be responsible for Li Chengqian's downfall, appointed yet another son, Li Zhi (also by Empress Zhangsun), crown prince instead.
Li Chengqian was exiled, and died in exile in 644, as a commoner under house arrest.
He was posthumously granted an imperial prince title during the reign of his grandnephew, Emperor Xuanzong after his grandson Li Shizhi became chancellor.
Empress Zhangsun
Empress Zhangsun (長孫皇后, personal name 長孫無垢) (15 March 601 – 28 July 636), formally Empress Wendeshunsheng (文德順聖皇后, literally "the civil, virtuous, serene, and holy empress") or, in short, Empress Wende (文德皇后), was a Chinese essayist and empress of the Chinese dynasty Tang Dynasty.
She was the wife of Emperor Taizong and the mother of Emperor Gaozong.
She was well educated, and her ancestors were of Xianbei nationality.
Their original surname was Tuoba, later changed to Zhangsun.
Li Tai
Li Tai( 620 – 20 January 653), courtesy name Huibao( 惠褒), nickname Qingque( 青雀), formally Prince Gong of Pu( 濮恭王), was an imperial prince of the Chinese Tang Dynasty.
Li Tai, who carried the title of Prince of Wei, was favored by his father, Emperor Taizong, for his literary talent and studiousness.
His older brother Li Chengqian was crown prince, but Li Tai and his associates had design on that position, eventually pushing Li Chengqian to plot treason in 643.
After Li Chengqian's plot was discovered, Li Chengqian was deposed, and Emperor Taizong agreed to create Li Tai the new crown prince.
However, Emperor Taizong soon saw that Li Tai had pushed Li Chengqian toward rebellion by machination and further appeared to bear ill intentions toward their younger brother Li Zhi the Prince of Jin, and so Emperor Taizong created Li Zhi crown prince instead.
Li Tai was reduced in rank and briefly put under house arrest, and then exiled.
He died in exile in 653.
The Buddhist statues in the Main Wall of Bingyang South Cave of the Longmen Caves was dedicated by Li Tai to his deceased mother Empress Zhangsun.

Yu Zhining
Yu Zhining( 于志寧)( 588–665), courtesy name Zhongmi( 仲謐), formally Duke Ding of Yan( 燕定公), was a chancellor of the Chinese Tang dynasty, during the reigns of Emperor Taizong and Emperor Gaozong.
He had served on the staff of Emperor Taizong's oldest son and crown prince Li Chengqian and, after Li Chengqian was removed for plotting to overthrow Emperor Taizong in 643, received approval for having tried to correct Li Chengqian in his ways.
Emperor Taizong promoted him, and he subsequently played prominent roles in the imperial government late in Emperor Taizong's reign and early in Emperor Gaozong's reign.
In 659, however, because he had previously not supported the ascension of Emperor Gaozong's second wife Empress Wu( later known as Wu Zetian), he was removed from his office based on accusations by her ally Xu Jingzong that he had conspired with Emperor Gaozong's uncle Zhangsun Wuji, who had opposed Empress Wu's ascension.
