The Sui Emperor and Tang Taizong were very similar. Both of them were second sons, and originally did not inherit the throne, but they both killed their brothers and became emperors themselves by their own efforts.
The Sui Emperor was a little more benevolent than Tang Taizong, he only killed his brother, not his brother, his brother rebelled, he did not kill, just put his brother under house arrest.
Both the Sui Emperor and Tang Taizong had the talent to want to do great things, but why did Tang Taizong become a generation of Ming Jun, and the Sui Emperor became a generation of Emperor Xia? This is because Tang Taizong learned the lessons of the Sui Emperor, who was more sympathetic to the people and regarded the people as water carrying boats. The Sui Emperor did not regard the people as people, regarded the people as tools for his own work, and when he did great things, he never sought the consent of the people, and even did not consider the people's ability to bear, the people could not bear it, the suffering was unspeakable, and he rebelled and overthrew his rule.
