Hanlin was first seen in the Tang Dynasty. Emperor Xuanzong of the Tang Dynasty established the Hanlin Academy, in which there was an academician to be enshrined by imperial edict. Later, he was also called Hanlin Bachelor, a literary squire. After arriving in Tang Dezong, he was in charge of confidential documents and tried to write the emperor's orders, but these documents were not obtained through examinations and were not official court officials. In the Song Dynasty, the status of Hanlin bachelor was further improved, and the Hanlin bachelor's college was established, which made the Privy Council, which was actually in charge of the government affairs hall (under Zhongshumen), occupy an equal position. Bachelor Hanlin learned that writing letters on behalf of the emperor is a full-time job, one of which is called "undertaking orders". Those who don't belong to Hanlin Nominal Bachelor's College include Bachelor of Work-study Program and Bachelor of Work-study Program. These so-called banquet officials take it as their duty to enter the history of books around the emperor. The emperor really needs to collect this batch of learned soil as a "think tank", so he is prepared to treat it as a favor. Since then, all the ruling ministers have awarded the honorary title of a temple university to show their respect. In the Ming Dynasty, Hanlin was selected from the Jinshi to assist the emperor in handling government affairs and became a formal official of the imperial court. In the Qing Dynasty, imperial academy was headed by a bachelor, and there were four officers: Staff Sergeant, Staff Sergeant, Staff Sergeant, Editor, and Editor.
