Yanling Dao in Ming and Qing dynasties is as famous for its system as Yanling. Yanling Dao appeared at the end of Yuan Dynasty and the beginning of Ming Dynasty, and its main shape was hand-held Dao in Song and Jin Dynasties. The handle and blade are straight, but influenced by Mongolian knives, so they are slightly inclined at the tip, but they are even less inclined than Mongolian knives.
Yanling Dao is the largest number of swords in Ming and Qing Dynasties. In Ming dynasty, it was commonly known as broadsword, and the broadsword of infantry could be equipped with shield. For the war in which firearms and cold weapons are relatively developed in mainland China, the quality of broadsword is not the key to victory or defeat. Therefore, most of the big swords are not made in fine steel, but the soft blade is poured out by pouring steel, and then a more delicate blade is clamped. Yanling Dao pays attention to practicality, not to look good. Yanling's blade is light, can be stabbed and cut, and has great lethality.
The basic design features of Yanling broadsword are that the blade body is straight, the tip of the blade is slightly upturned into an arc, and there are many pieces from the tip to the back of the blade at 15-20cm. Now it is generally called anti-blade (some Yanling broadswords in the middle and early Ming Dynasty have no anti-blade, which is closer to Jin Jian style in form, while some Yanling broadswords in the Qing Dynasty even run through the back of the blade).
The blade width is 4-5cm, the ridge thickness is 0.6-0.7cm, the blade section is isosceles triangle, the total length is about 90cm, the blade length is 70-80cm, the handle length is 15-20cm, and the total weight of the blade is 1-0.5 kg. The Ming Yanling broadsword has/kloc.
There are many styles of official Dao in Ming and Qing Dynasties, with Yanling, Yanyi and fish head as the mainstream, as well as goose feather, Qijia (imitating Japanese waist Dao) and oxtail (appearing in the late Qing Dynasty).
Among them, Yanling is the mainstream. Although Yanling and Mao Yan have similar names, their blade shapes are quite different. Mao Yan Dao has not been handed down from generation to generation, and the reason for its blade formation is still controversial. However, Yi Yan Dao can be said to have inherited Song Dao, and then began to machete (such as the anti-Japanese broadsword in the Republic of China), and its blade shape is also worth studying.
Compared with Yanling Dao, the shape of word-difference Yanyi Dao is rougher.
