It is said that it is the most ruthless imperial family. Throughout Chinese history, in order to compete for the throne, brothers fought and siblings, and even killed their fathers and brothers, which happened in almost every dynasty. Moreover, in order to be able to sit safely in the country, some emperors did not hesitate to kill their competitors and achieve the purpose of cutting grass and removing roots.
For example, the famous Xuanwumen Revolution, which took place at the beginning of the Tang Dynasty, was a military coup that Li Shimin had planned for a long time to seize the succession to the throne from his brother Li Jiancheng.

After Emperor Gaozu of Tang ascended the throne, li Jiancheng was made crown prince and made him permanently stationed in the palace to handle affairs, and he became the representative of the civil official clique. Li Shimin, on the other hand, was the King of Qin, and he continued to lead the wu general group to lead the army, and at the same time, he also made the greatest contribution in the process of conquest.
Therefore, Crown Prince Jiancheng knew that his military achievements and prestige were inferior to those of his younger brother Shimin, so he was afraid that the crown prince's position would change, so he joined forces with another younger brother, Li Yuanji, the Prince of Qi, to exclude and frame Li Shimin. At the same time, Li Shimin's clique also disobeyed the prince, so the two sides began a continuous open and secret struggle.
After a long struggle, under the favor of Li Yuan, the Li Jiancheng clique gradually gained the upper hand and controlled the situation. In order to save the situation, in the end, Li Shimin could only fight for his life, launched a mutiny at Xuanwumen, killed his eldest brother Li Jiancheng, the crown prince of Qi, and his fourth brother Li Yuanji the Prince of Qi, and Li Shimin also forced Li Yuanli, the emperor of Tang, to make himself the new crown prince, and later inherited the emperor's throne, for Tang Taizong, whose era name was Zhenguan.
However, speaking of this vigorous mutiny, there was a famous general who became invisible in the xuanwumen change, and he was the famous Qin Qiong. Then, why did Qin Qiong, the change of Xuanwu Gate, go invisible? Only because of Li Jiancheng's number one fierce general, only he can resist!
The folk custom of sticking the door god during the New Year has a long history, that is, at the time of the New Year, the portraits of Qin Qiong and Wei Chigong are pasted on the door of their own homes. The origin of the portraits of chi gong and Qin Shubao, the current door god, is that in those years, because Li Shimin was afraid that the ghosts of the two brothers he had killed would come to ask for his life, he sent the two to serve as guards in front of the door, and this was passed down. However, in the change of Xuanwu Gate, Wei Chigong made a great contribution, which is well known to everyone, but what did Qin Qiong do? I think many people are not very clear, and some people even say that Qin Qiong is not involved in it at all. What is the truth like?
Qin Qiong(秦 Qiong), courtesy name Shubao, was a native of Licheng, Qizhou, and he was a famous general in the late Sui and early Tang dynasties. Qin Qiong was originally a Sui general, and successively served under Lai Hu'er, Zhang Sutuo, and Pei Renji, and was known for his bravery and martial prowess. Later, he followed Pei Renji to Li Mi, the leader of the Wagang Army, and after the defeat of Wagang, he switched to Wang Shichong, but because he saw that Wang Shichong was treacherous, he defected to Li Tang with Cheng Yaojin and others.
After surrendering to Tang, Qin Qiong accompanied Li Shimin in his southern expedition to the north, and was a fierce general who could take the first rank of the enemy general in the Wanma Army, but he was also wounded because of this. After the unification of Tang, Qin Qiong was plagued by a long illness and died of illness in the twelfth year of Zhenguan. After his death, he was posthumously awarded the title of Governor of Xuzhou and Duke of Huguo, known as "Zhuang". In the seventeenth year of Zhenguan, he was listed as one of the twenty-four meritorious servants of Ling Yan Pavilion.
According to the Old Book of Tang, whenever Shu bao conquered from Emperor Taizong, there were sharp pawns in the enemy, showing off people and horses, and those who came and went, and Emperor Taizong was quite angry, and ordered Shu Bao to go to get it. Shu Bao answered the order, the Prancing Horse marched with a gun, and among the multitudes that would stab him, the people and horses were easy, and Emperor Taizong thought that it was beneficial, and Shu Bao was also quite self-effacing.
From this point of view, once it is an opponent that is difficult to deal with, Li Shimin will let Qin Qiong go out to fight, so how can a big event like the change of Xuanwu Gate not let Qin Qiong be responsible for some important work?
According to the Old Book of Tang, on June 4, from Jie Jiancheng, Yuan Ji. Shi Ning, the Great General of Zuo Wuwei, sealed seven hundred households.
Obviously, Qin Qiong must have participated in the change of Xuanwu Gate, otherwise why would he be rewarded after the matter was over? The question, then, is what Exactly Qin Qiong did, and why is there little record of it.
According to the "Old Book of Tang and the Biography of Changsun Shunde", "In the ninth year of Wude, (Changsun Shunde) and Qin Shubao and others discussed the establishment of the Yu Dang at Xuanwu Gate."
It turned out that Qin Qiong was really entrusted with an important mission, when Li Shimin and Wei Chigong and others ambushed Li Jiancheng and his reinforcements, li Shimin's troops at this time were far from enough to clash head-on, so someone had to guard outside the gate, and Qin Qiong was entrusted with this heavy responsibility, he needed to face a large number of reinforcements, as well as the powerful Li Jiancheng's general - Xue Wanche.
After hearing the news of the prince's death, Xue Wanche led 2,000 elite soldiers to attack Xuanwu Gate, while Qin Qiong led the gatekeepers to fight hard. Xue Wanche saw that he could not attack for a long time, so he wanted to lead an army to attack the Qin Mansion and take his wife and children, and the Qin Generals were terrified when they heard the news. At this time, Wei Chigong arrived in time, holding Li Jiancheng and Li Yuanji's first rank to show the public, the other side's soldiers collapsed, and Xue Wanche had to lead dozens of horses to escape.
And because it only delayed the time, it was not as good as Wei Chigong's merits, so there was almost no record, which was also the reason why Qin Qiong was invisible.
