Tangdao, as an exquisite cold weapon, although expensive, played an important role in the war of the Tang Dynasty because of its portability and powerful lethality. Especially in cavalry combat, tangdao is light and flexible, which can better help soldiers exert their power and annihilate the enemy.
Since tangdao had so many advantages, why wasn't he hated in the Song Dynasty? We can first understand the development after the rise of the Song Dynasty, and then we can know why cold weapons were eliminated by the times, which has both the influence of social development and the influence of war demand. The Song Dynasty, which replaced the rise of the Tang Dynasty, was highly appraised in history and was the most prosperous period of feudal society.
However, the military ability of the Song Dynasty was not very high, and even it was often invaded by foreign enemies, especially some ethnic minorities lurking around, such as Xixia, who were always eyeing up.
Although the research and development of military weapons in the Tang Dynasty reached its peak at that time, and some amazing masterpieces appeared, which played an important role in the war at that time, the Song Dynasty did not follow the Tang Daofa. On the battlefield, we seldom see tangdao used by Song people, and this kind of prop is almost extinct.
As mentioned above, Tang Dao was well used for cavalry, but there were not many cavalry in the Song Dynasty, to be exact, there were very few cavalry. That's not all. No horses. That's the big problem. It is said that there was no place to raise horses at that time in Song Dynasty, and many vast grasslands were basically occupied by the surrounding ethnic minorities.
According to statistics, the number of horses raised in the Song Dynasty was as high as 200,000, but this figure was only half that of the Tang Dynasty. It is conceivable that the Song Dynasty didn't even have the premise of using it under such circumstances, so why did tangdao come?
