A college student was not an official position, similar to the current degree. Because in the middle and late period of China's history, officials (especially big officials) always showed their high level of knowledge, and a college student was the highest academic record. For example, the prime minister of the Song Dynasty was also a college student, and Bao Zheng was a college student in Longtuge.

Later, in the Ming and Qing Dynasties, college students were no longer "degrees", but were awarded the titles of ministers who entered the highest decision-making bodies-the cabinet and military departments of the Qing Dynasty, which was actually the biggest official title. For example, Liu Yong and Ji Xiaolan are called college students on TV.

As for the prime minister, it refers to the highest official title in China, not the actual official name. Including the prime minister of the Han Dynasty, the governors of the three provinces of the Tang Dynasty, the Tang envoys of the Song Dynasty, and the university students of the Ming and Qing Dynasties. Therefore, college students were prime ministers in Ming and Qing Dynasties. For example, the so-called "Prime Minister Liu".
