What was the system of employing people and taking scholars in the Tang Dynasty?

The long national movement and relatively stable political situation in the Tang Dynasty created conditions for the development of the imperial examination system. On the one hand, the Tang Dynasty required local officials to recommend talents with both ability and political integrity to the imperial court, on the other hand, it actively promoted the imperial examination system, gradually expanded the examination subjects, increased the examination contents and improved the examination procedures, so that the imperial examination system replaced the system of recommending and selecting talents and became the system of selecting talents ahead of all countries in the world at that time.

During the reign of Emperor Taizong, the cultural and educational policy of suppressing Wu Xiuwen was implemented. It not only revitalizes education, expands schools and builds school buildings, but also trains reserve talents for the country to ensure the quantity and quality of imperial examination candidates. At the same time, it also vigorously promoted the imperial examination system, offered courses and recruited talents to achieve the goal of consolidating the Tang Dynasty.
