The measures taken are: the great achievements of Emperor Taizong.
1. He uses people in an eclectic way, and his use and leadership of talents have reached a very high level;
2. He has a unique eye, saw the lack of personal strength, fully realized that only a king is like a stone, a good minister is like a craftsman, and humbly adopted the minister's progressive words;
3. A political management system with separation of powers and mutual supervision has been initially established, stipulating that government decrees and even government decrees themselves (parts that affect national policies) can only take effect and be issued after being examined and countersigned by provincial organs, thus ensuring the feasibility of policies, finding and correcting them in time, and putting an end to the harm and influence of bad policies on the country and people;
4. Recognizing the legal and political policy of putting human life first, it is stipulated that the death penalty can only be executed after three repetitions (five repetitions elsewhere). People think that only 29 people were sentenced to death in the fourth year of Zhenguan (630), and 290 people were sentenced to death in the sixth year of Zhenguan (632). These 290 people were ordered to go home for the Youth League and come back for retrial after the autumn harvest next year. This is not difficult to identify.
