In the Song Dynasty, there were several kinds of mirror armor, such as steel chain armor, black lacquer near the water mountain spring armor, Mingguang fine mesh armor, Mingju armor, and step person armor. The "History www.biquge.info of the Song Dynasty and the Chronicles of the Soldiers" records that the total weight of a set of mirror armor in the Song Dynasty is 45 to 50 catties, and the nail leaves have 25 pieces of flying, and the manufacturing time is 120 working days, and the cost is three and a half times. The Ming Dynasty focused on reducing the amount of mirror armor, and each payment was reduced to 40 catties to 25 catties, mostly iron valve mail and chain mail

The Song Dynasty infantry armor was the main equipment of the heavy infantry of the Song Dynasty. The Song Bu Armor was developed on the basis of the Tang Infantry Armor, and the whole body was covered with scale armor and weighed 20-30 kilograms. Due to the loss of horse-producing areas in the north, it was not possible to equip cavalry in large quantities like the Han and Tang dynasties, while the Song mainly relied on heavy infantry in infantry armor. A thick line of infantry composed of heavy infantry in infantry armor could effectively resist the attack of cavalry, but the biggest disadvantage of heavy infantry was the lack of mobility, the inability to effectively pursue the enemy in the event of victory, and the inability to retreat in time in case of defeat, as can be seen in several battles of Song Jin.

Although the impression of the Song Dynasty to later generations was that it emphasized literature over military force. But what is less known is that the Song Dynasty had the best protected hoplites in ancient China, and they were armed with super-heavy Song Dynasty infantry armor.

In the Song Dynasty, European chain mail weighed only 15 kilograms, and in the 15th century, Gothic full-body armor weighed only 20 kilograms. Although the heaviest armor in the 17th century reached 42 kg, the average heavy three-quarter armor was only in the range of 20-30 kg. In terms of weight, the infantry armor of the Song Dynasty of China is the heaviest armor in Chinese history, and according to the "General Essentials of the Wujing", the Northern Song Dynasty Buren armor is made of iron armor leaves with * or nails, which is a typical armor. Its protection range includes the whole body, and in terms of protection range, it is the closest to the Chinese armor of European heavy armor, but it has not reached the impermeable level of protection of European heavy armor.

According to the regulations of the fourth year of Song Shaoxing (1134), the Buren armor is composed of 1825 armor leaves, with a total weight of 29kg, and the protection can be improved by increasing the number of armor leaves, but the weight will increase further. For this reason, the emperor personally ordered that the infantry armor should be limited to 29.8kg. After that, the weight of the armor of the pikemen was set at 32-35 kg; Since the archers were often involved in melee combat, their armor was set at 28-33kg; And the armor of the crossbow shooter was set at 22-27kg. At the same time, the type of armor of the European infantry cavalry was mainly chain mail, which did not reach such a weight
