At the end of the Tang Dynasty, eunuchs were also authoritarian, but the eunuchs at the end of the Tang Dynasty were even more arrogant and even dared to kill the emperor (Tang Xianzong was killed by eunuch Chen Hongzhi and Tang Jingzong was killed by eunuch Liu Keming). In the last five dynasties and ten countries split, and the two dynasties were interrupted. There was a new Mang regime in the middle of the Han Dynasty and a Wu Zhou regime in the middle of the Tang Dynasty. These two regimes did not exist for a long time. The difference is that after the demise of Xinmang, there are also troubled times and Liu Xiuhua.

At the beginning of Han Dynasty, Liu Bang practiced the policy of recuperation for decades, and then "the rule of culture and scenery" appeared. Both dynasties are said to be prosperous times in China's history, and the country is strong and famous, such as the rule of literary circles in the Han Dynasty and the rule of Zhenguan in the Tang Dynasty; There were Emperor Wudi, Korean and Han Jing in the Han Dynasty, and Emperor Taizong and Emperor Xuanzong in the Tang Dynasty. It reached its peak during the reign of Emperor Wu of the Han Dynasty, and in the Eastern Han Dynasty, there was a situation of "martial arts revival".

Defeated by the Tang Dynasty. The difference between the Tang Dynasty and the Han Dynasty is Koguryo in Liaodong, which is a great disaster to the northeast border. The Western Han Dynasty was usurped by Wang Mang, who proclaimed himself emperor. Having one's own title means the demise of the Western Han Dynasty. In the reign of Wang Mang 16, Luoyang was its capital, which was called the Eastern Han Dynasty in history and the Western Han Dynasty in the past. The Tang Dynasty was usurped by Wu Zetian and founded in the Zhou Dynasty. After more than ten years, the Tang Dynasty was restored and the capital was still in Chang 'an, so it was not called two periods. Liu Xiu established a new dynasty and overthrew the follwed dynasty through armed uprising. At this time, the dynasty changed. Koguryo was founded by Fuyu people, an ancient tribe in Northeast Asia. It is said that he is a descendant of ji zi in Shang Dynasty.

If "Tang" Li ruled for a longer time and had a wider territory, the difference is that the emperor before Wu Zetian was her husband Li Zhi, and the emperor after Wu Zetian was her son Li Xian. If the reputation is more prominent, it is worthy of a "big" word and can be tied with Tang Yuan of the "Datang".
