China ancient feudal society has a long history. In the long history, the dynasty regime has changed several times. The reason lies in whether the ruling policies pursued by emperors won the hearts of the people, and the enlightened way of governing the country has always been the pursuit of emperors in previous dynasties, but few have really succeeded in this respect. The rise and fall of a year lies in the law of governing the country. Those who are enlightened prosper and those who are occluded die. The theory of "Zhenguan rule" was a prosperous time under the rule of Emperor Taizong and Li Shimin. Although the means used by Emperor Taizong and Li Shimin to ascend to the throne were extremely cruel, his outstanding political talent is undeniable. During his reign, the prosperity of the Tang Dynasty depended on his outstanding leadership and rigorous work style. On the other hand, his open-minded attitude and his ability to coach are particularly important. In "Seeking Advice", he repeatedly mentioned various measures he took to encourage his subjects to actively make suggestions, such as: "Anyone who makes suggestions must have an illusory heart", and Wei Zhi set an example for ministers and encouraged them to make more suggestions, and so on. In feudal dynasty, it was not easy for a king to do this. It can be seen that the monarch's enlightened way of governing the country is very important to promote the rise and fall of the dynasty. This year is the 90th birthday of China Producer Party. * * * The reason why the Productive Party was able to lead the people of the whole country to the three mountains that were pressing on the people's heads and win the eight-year War of Resistance against Japanese Aggression and three-year civil war was the result of the concerted efforts of the people of the whole country, Qi Xin, who verified the sentence "He who won the world won the hearts of the people" and the wise way of governing the country by the Productive Party. From another point of view, there are countless examples of the collapse of the dynasty due to the fatuous tyranny and arbitrary dictatorship of the emperor. Xia Jie's wanton and tyrannical tyranny destroyed the Xia Dynasty. Shang Zhouwang didn't listen to advice, so he spoiled da ji and destroyed the Zhou Dynasty. Qin Ershi's fatuity and incompetence led to the treacherous court official being in power in Qin Dynasty, and there was no place for loyal officials, which also ruined Qin Shihuang's painstaking foundation. Throughout the ages, many dynasties have fallen because of this. Perhaps the crisis facing the outside of the dynasty is part of the reason, but the fundamental reason is that the fatuity of the king leads to political corruption within the country, just like insects eat trees. Insects eat bark and don't kill trees, but eating roots is the essence that causes trees to die.
