Old Tang Shu (Volume 9), New Tang Shu (Volume 5) and Tang Shu (Volume 5) are considered to be the only daughters of grandchildren.

"Don Yao Hui" Volume 6 "Princess He Fan" is considered as the niece of Dugu;

Zi Tongzhijian (Volume 2 15) and Yuan Gui (Volume 979) are considered to be the granddaughters of Dugu;

The article "Khitan Merchants" in the Book of the New Tang Dynasty (Volume 2 19), Biography of Khitan, General Examination of Literature (Volume 344) and Examination of the Four Dynasties (Volume 22) is considered to be the only one who came from an imperial clan.

With regard to the first statement, Cui Mingde wrote in the History of Intimacy in Ancient China (hereinafter referred to as the History of Intimacy): "Xuanzong of Tang Dynasty was born in August of the first year of Hanggong (685), and March 6 of Tianbao four years (745)1year old. It is against common sense to have a married granddaughter at the age of 6/kloc-0. So the so-called "grandchild's daughter" is obviously the mistake of "granddaughter's daughter". "

Regarding the second statement, if you look up the Book of the New Tang Dynasty and the Princess of Tang Dynasty, Tang Ruizong has 1 1 daughters, but none of them married Dugu. Thus, Jingle Princess Dugu is not the niece of Emperor Xuanzong of Tang Dynasty, and the second statement is not valid.

Regarding the third statement, The History of Intimacy and Intimacy wrote: "With regard to the life experience of Princess Dingdang, Princess Dingdang's surname is Dugu, ..., and then according to the Biography of Princess in the New Tang Dynasty, it can be known that Emperor Xuanzong of the Tang Dynasty had 30 daughters, ... and the fifteenth woman believed that the princess was married to Duguming. It can be seen that Princess Tinker Bell was born to a new city princess. Therefore, Princess Dingdang is the granddaughter of Emperor Xuanzong of Tang Dynasty. "

Is the Duchess of Jingle Princess the daughter of Princess Xincheng and Du Guming? The key lies in whether Princess Xincheng and Du had a daughter when Princess Jingle Du Gu got married in March of the fourth year of Tianbao (745).

"The Book of the New Tang Dynasty" Volume 83 "Princesses of Past Dynasties" contains: "Believe in the princess and marry Du Fu."

"Book Letter into Princess Wen": "In the twenty-fifth year of Wei Kaiyuan (737), Ding Chou was born in August, on the fifteenth day of the first month, Ding Si, and the emperor said: Yu!" Yi is about returning home, and Poetry is about marrying, so it is decadent and ethical. ..... book, for the letter into a princess. Guang Qi shows its virtue and has a national style. He is blessed if he is not lazy, but he can be careless! "

Princess and princess registration is the first procedure for the princess to come out. The book is the name of the princess, and it is also a formal written document that allows the princess to surrender. So the princess's conferring preceded her surrender.

Princess Xincheng was registered on August 15th in the 25th year of Kaiyuan (737). Princess Xincheng and Du Yu got married after August 15th in the 25th year of Kaiyuan (737).

By March of the fourth year of Tianbao (745), Princess Xincheng and Du could not get married at the age of six and a half if they had daughters. It is untenable to say that Princess Jingle was born to Princess Xincheng and Du, the 15th daughter of Emperor Xuanzong of Tang Dynasty.

The first three statements were rejected, leaving only the fourth statement.

The Book of the New Tang Dynasty (Volume 2 19) and Biography of Qidan contain: "In the fourth year of Tianbao (745), Li Huaixiu, the chieftain of Qidan, surrendered, worshiped Song Mo as governor, made Feng Chongshun king, and took the imperial clan as the wife of Jingle Princess."

The article "On Qidan" in Wen Tong Kao (Volume 345) and Twenty-two Kao of Four Dynasties wrote: "In the fourth year of Tianbao (745), Li Huaixiu, the chief of Qidan, surrendered, worshiped Song Mo as the governor, and Feng Chongshun as the king, and took the imperial clan as the wife of Jingle Princess."

Literature General Examination is an important work of Ma Duanlin, a famous scholar in Song and Yuan Dynasties. A General History of Laws and Regulations from Ancient Song Dynasty to Ningzong Period, one of the ten biographies, was written in the 11th year of Yuan Dade (1307).

Ma Duanlin has written Old Tang Book, New Tang Book, Zi Tongzhi Jian, Original Rules of Ci and Fu, etc. It is reasonable and thought-provoking why Princess Dingdang's life story is based on the Book of the New Tang Dynasty and the Biography of Qidan, rather than others.

The History of Intimacy and Intimacy also said: The History of Intimacy and Intimacy and the Identity Table of Married Minorities and Intimacy Princes in the Central Plains Dynasty listed the identity of Princess Jingle Dugu as "imperial niece". The "imperial niece" is not a granddaughter or a niece, but an "imperial niece".

Jingle princess Dugu is not the daughter of Xincheng princess, nor the granddaughter of Emperor Xuanzong of Tang Dynasty, but the imperial clan daughter.

Qin Qin background Khitan can suddenly rebel, and Li T broke it in the Tang Dynasty and captured many people. But suddenly, he led his troops away, everyone fell, and Li T returned. A year later, he suddenly returned, and Xue Chuyu sent Guo Yingjie and others to pursue him and was defeated. Zhang Shou was regarded as a long history of Youzhou in the Tang Dynasty, which was taken lightly by Cheng Yi. However, he was forced by Zhang Shou, sent a fake surrender, was surrounded by soldiers, and defeated Lee Guo in Qidan. Zhang Shou ordered Lee Guo to unify the Khitan people. After that, Lee Guo was killed by the remnants of the Party, and Zhang Shou led an army to break the Khitan.

In the fourth year of Tianbao (745), Li Huaixiu, the great chieftain of Qidan, surrendered, and was made the commander-in-chief at the end of the Song Dynasty and the king of Chongshun. On March 14th, the fourth year of Tianbao (745), Xuanzong married Li Huaixiu, a Khitan, and took the fox family as a quiet princess. By September, An Lushan had repeatedly invaded Xi and Qidan to carry out border work, which led Qidan to kill Princess Jingle and rebel against the Tang Dynasty.

After the Anshi Rebellion, the Khitan frontier fortress, Lee Jae-yong of the Tang Dynasty repelled the Khitan and captured the famous Khitan king. Liu Ji defeated Xi, chased Du Qingshan for more than 1000 miles and beheaded 20 thousand people. Zhang Zhongwu broke through the northern part of Xi and Shaanxi.

Historical Data Zi TongZhiJian Volume 2 15:

From Xuanzong to Emperor Daming, the great sage of Taoism, Tianbao lasted for four years (AD 745).

In March, Ren Shen married her eldest grandson, Dugu, as Jingle Princess, and Li Huaijie, King of Qidan. My nephew Yang is a princess and married Wang Liyanchong.

......

An Lushan wanted to attack the city with edge work and invaded Xi and Qidan several times; Xi, Qidan each killed the princess to rebel, and Lushan tried to break it.
