Emperor Gaozong of Tang. Li Zhi was an underrated emperor, a Tang emperor who was overshadowed by the light of Li Shimin (his father) and Wu Zetian (wife). We know that Emperor Taizong of Tang once led his troops to conquer Goguryeo, but in the end failed to subdue the country. After Li Zhi took the throne, he successively sent troops to attack the Korean Peninsula and destroyed Goguryeo and Baekje. Li Shimin once destroyed the Eastern Turks, and Li Zhi continued to wipe out the Western Turks. He attaches great importance to solving farmers' problems. Because he was diligent in government affairs, he was "the people of Fu'an, and there was a legacy of zhenguan", which is called "the rule of Yonghui" in history, and his merits were not inferior to that of Tang Taizong.
Zhao Zhen, yes, he is the protagonist of the tanuki cat for the prince in the drama. This emperor has always been known for his wisdom and benevolence, and it is said that after his death, both the major officials of the DPRK and China and the common people were very sad, and even consciously put on filial piety hats for him, which shows the high image of him in the hearts of the people! During his reign, he was always very open to accepting the opinions of his ministers, and he was also very tolerant, such as Bao Zheng in front of him and even dragged the emperor's sleeve to prevent the emperor from leaving, but he still listened to Bao Zheng's opinions.
The Sui Wen Emperor Yang Jian was the founding emperor of the Sui Dynasty, and his sense of existence in China has not been high, but he is considered by Westerners to be the emperor of China through the ages.

It was he who ended More than 300 years of war in China and saved the Chinese nation from danger. In which gray era, if it were not for the Sui WenDi who unified China, there would be no prosperity during the Tang and Song dynasties.
Yang Guang. Yang Guang was also blackened, such as father-killing, incest, alcoholism, labor, indiscriminate endowment, military service, conquest, abuse, betrayal of officials, untrustworthiness, etc., and the proper representative of the emperor eventually perished. Although Yang Guang was a subjugated monarch, he was not an incompetent person, on the contrary, he was a far-sighted person with great political and ambitions.
