At present, bachelor's degree, master's degree and doctor's degree are called degrees respectively, among which bachelor's degree is bachelor's degree, master's degree is master's degree or graduate student, and doctor's degree is higher than graduate student's degree, so he must pass the corresponding examination. The graduation of these three degrees requires dissertations to prove that their learning results are excellent enough to be awarded diplomas. But now many college students can't find jobs in society, so they still have to study for a higher degree.
Ancient doctors should first appear in the Spring and Autumn Period and the Warring States Period. At that time, doctors were the people in charge of documents. Later, in the Tang Dynasty, the meaning of doctor expanded, referring to having deep attainments in a certain subject; After the Song Dynasty, the scope was larger. Dr. Cha can often be seen in novels, which shows that the scope of Dr. Cha has been derived to people who have made certain achievements in any field. It can be said that the gold content is getting lower and lower and more common.
Master's words, as mentioned above, have no specific meaning. Mainly about bachelor's degree, the word also appeared very early, and in the Wei and Jin Dynasties, there was such an official position. At that time, it was just to supplement the literature. By the time of the Tang Dynasty, the status of the bachelor had become much higher, which means that the people who gave advice to the imperial court really participated in the imperial court, especially the Hanlin bachelor, and it was very important. At that time, the emperor not only listened to the opinions of the court ministers, but also listened to the opinions of the bachelor.
