What is most worth mentioning, however, is that although the military power of the Tang Dynasty was strong, it was strong, systematic and cultured, and it was neither militaristic nor lax in military affairs.
According to "Zhenguan dignitaries":
Emperor Taizong said: A soldier is a sharp weapon of the country. Although the land is vast, belligerence will kill the people; Although China is safe, it is dangerous if people forget to fight. Withering is not a technique of preservation, and it is hardly a prescription of imitation. Can not be completely removed, can not be used frequently. Therefore, the agricultural gap talks about martial arts, and Xi Wei Yi also; Run the army for three years, distinguish ranks, and take Gou Jian's frog as the basis. Abandoned Wu and eventually lost his country. What is this? The more you learn, the more you forget.
Confucius said, "If you don't teach the people to fight, you will abandon them." So we know the power of sharp arrows to benefit the world, which is also the position of fighting.
The Tang Dynasty was an outstanding dynasty in the history of China. Powerful military power is a remarkable feature of the Tang Dynasty. The Tang Dynasty unified China, which was separated by warlords at the end of Sui Dynasty. When Emperor Taizong and Wuhou were in power, they made expeditions to East and West Turkistan, destroyed Gaochang and took it as a county, destroyed Koguryo and Baekje, defeated Japanese reinforcements in the battle of Baicunjiang, and fought against Hong, Tiele, Shiwei and Qidan. At that time, the military system, economy and scientific and technological advantages of the Tang Dynasty in Asia were the basis of these achievements. During the reign of Emperor Xuanzong of the Tang Dynasty, the forces of the Tang Dynasty met the forces of the Abbasid Dynasty (that is, the black food) from today's Arabia, and the emerging Sunnis believed in Islam in Central Asian countries, including Zhaowu, nine planets, Polo and Tuhuoluo. As a result, after the Tang Dynasty was defeated in the battle of Pilars, China's forces withdrew from Central Asia. The ensuing Anshi Rebellion and the separatist regime in the buffer regions led to the economic depression in North China and Hu Hua.
Among the many famous generals in the Tang Dynasty, in addition to the twenty-four masters of Lingyange, Li V, Gao Pian and other generals in the Han Dynasty, foreign generals also occupied an important position: the more important ones were Lushan, Shi Siming, Chang Zhi with black teeth of Baekje, Gao Xianzhi of Goguryeo, Li Guangbi of Qidan, Li Huaiguang of Mohong, Ge and Tie of Turkic history, etc.
