Qintianjian, a mysterious department in history, has influenced the development of history many times.

The Qin Tianjian in "Ruyi's Royal Love in the Palace" must be hated by many people who follow the drama. Among them, the fate of the ten princes and the alienation of Ruyi's relationship with the emperor seem to be ""Qin Tianjian"" It has become a turning point in the fate of the characters in the play. This role is rare in previous film and television dramas, and it is also relatively mysterious. Let’s learn about the real “Qin Tianjian” in history. This mysterious royal department, It was called Sitiantai in the Tang Dynasty, Sitianjian in the Song Dynasty, and Qintianjian in the Ming and Qing Dynasties. It was equivalent to today's astronomical observatory. After all, in history, it is not accurate. In addition to astronomical stargazing, calendaring and divination, there is also Kanyu (Fengshui culture). Kanyu practitioners work in parallel with the Five Elements experts to observe the sky, survey the geography, and make plans for the construction of royal tombs in the hereditary Qintianjian Ming Dynasty. Before the mid-term period, the household service law of "assigning households to serve as errands" was adopted, following the old system of the Yuan Dynasty, and was divided into several types of household registration, mainly including civilian households, military households, craftsmen households, and kitchen households. Qintianjian was an institution that served the imperial power. Therefore, the Ming Dynasty had special regulations for the management of talents in Qin Tianjian, such as "" is included in the law and is never allowed to move. The descendants can only learn astronomy and calculus, and are not allowed to learn other professions; those who do not study are sent to the Nanhai Army." It is not surprising that the families of officials in the Qintian Prison are hereditary. In Nanjing, there are several well-known families. According to the "Wu Family Genealogy", Wu Ru, the ancestor of the Wu family, was proficient in calendar and astronomy. 1369) came from Samarkand, Central Asia, and came to Nanjing to serve as the Qin Tianjian. Since Wu Ru, the Wu family has served in the Qin Tianjian for six consecutive generations, and there are "" doctorate officials. The reputation of "Six Dynasties". In addition, the more famous ones are the Bei family in Nanjing, among which Bei Lin (1429 ~ 1482), an astronomer in the Ming Dynasty of China. The courtesy name is Zongqi, and the name is Zhuxi Zhuosou. A native of Dinghai, Ningbo, in the early years of Hongwu, Taizu of the Ming Dynasty. His father was a soldier and moved to Nanjing. He was born in Nanjing. The most famous book "Qizheng Pushibu" contains a large number of stars and constellations. These stars are concentrated in 15 constellations near the ecliptic, including: Pisces, Aries, Sea Beast, Taurus, Human, Yin Yang, Cancer, Leo, Gemini, Libra, Scorpio, Serpent, Sagittarius, Capricorn, and Aquarius. Among them, Human, Serpent, and Sea Beast are not found in modern Western constellations. It can be said that 500 years ago, China had already conducted research on Western constellations. In the thirty-first year of Hongwu (1398), the emperor's grandson Zhu Yunwen succeeded to the throne as Emperor Jianwen, and Zhu Yuanzhang regarded him more highly. Under the planning of monk Dao Yan, his son Zhu Di raised an army in the first year of Jianwen (1399) and seized the throne in what is known as the "Battle of Jingnan" in history. After Zhu Di entered Nanjing, the former Jiangnan scholars performed differently, the most prominent Representatives include Fang Xiaoru, Lian Zining and others, who were staunchly loyal to the old emperor and refused to surrender and were killed; the other is Jingqing, who pretended to cooperate. During Jingqing and Hongwu years, he was a Jinshi, an editor of the Hanlin Academy, and later served as a supervisory censor, and was an honest official. Jing Qing, who pretends to cooperate, never forgets the kindness of his former emperor. He often hides his sword in his clothes, always waiting for the opportunity to stab him with a fatal blow. Everything was ready, but heaven and earth failed, and all plans were shattered by an urgent report from officials in Qintian Prison. Zhu Di received a secret report that the officials of the Qin Tianjian saw the celestial phenomena and found that the Wenqu star violated the emperor's throne. The new emperor's order was red. Someone wearing red was approaching, and the emperor should be careful. In August of the fourth year of Jianwen, Emperor Zhu Di came to the palace. Seeing that all the officials in the court were wearing standard court uniforms, but Jing Qing was wearing red clothes, Zhu Di was wary. After retreating from the court, the guards who were ambushing him took Jing Qing into custody and found the sword. Jing Qing scolded Zhu Di angrily. Zhu Di was furious and ordered the executioner to execute Jing Qing Lingchi. Qin Tianjian predicted the assassination in advance, and Zhu Di successfully escaped. This became Qin Tianjian's recorded highlight moment in the Ming Dynasty. Not only after seizing the throne, during the reign of King Yan, troops were launched in the "Battle of Jingnan", and the Qin Tianjian also had information to refer to. At that time, the Qin Tianjian saw changes in the sky and said that bandits were coming from the north and were invading the throne from the south. The throne was in danger. ". Zhu Di was hesitant. "The chief planner of the "Jingnan Campaign", Dao Yan, seized the opportunity. He said, "If the invaders from the south are not barbarians, then who are they?" The King of Yan randomly and decisively sent troops, opening the door. In 1449, the "Tumu Fort Incident" shocked the established development trajectory of Ming Dynasty. The Emperor Yingzong of the Ming Dynasty, Zhu Qizhen, personally conquered Wala and was defeated and captured.

Wang Zhen, the great eunuch who was in charge of the Supervisor of Ceremonies, wanted Yingzong to lead an army of 500,000 soldiers to march in person. However, the ministers of the DPRK asked Yingzong to station himself in the capital and send another general to go on the expedition. The two sides were at a stalemate, and the military situation was extremely urgent. Qin Tianjian became the final reference for strategic decision-making. The Qin Tianjian made further remarks, claiming that he watched the sky at night and saw that the stars were shaking, and that the assistants, prime ministers, captains, and prime ministers had all left. He believed that "this is God's will, and the chariots cannot stay". He also said to the officials: "My lord, wait for me." If you want to be loyal to the emperor and patriotic, you must establish Chu Er early to secure the foundation of the country. "In the end, Yingzong led an army of 500,000 soldiers to fight in person. As a result, Tumubao was defeated. The British Duke Zhang Fu and others were killed in the battle. The eunuch Wang Zhen died in the rebellion, which led to the accession of Daizong and the restoration of Yingzong. Qintian The prison seems to have played a negative role in the "Tumu Fort Incident" that the minister was embarrassed about. However, the celestial phenomena are like this. However, if it can be interpreted objectively, it seems to violate the law of seeking good luck and avoiding disaster. Knowing that there is a tiger in the mountain, you can also avoid it. There is a suspicion of political coercion of the Qin Tianjian to misinterpret the celestial phenomena. After the "Ziwei Dou Shu" was scattered among the people, the Qin Tianjian was established in Beijing and Nanjing. The former Nanjing officials of Tianjian fled the war and began to live in seclusion. At this time, the first divine art "Ziwei Dou Shu" began to spread among the people. Among them, the Southern School of Zhongzhou School is the inheritor.
