What kind of bow was used in ancient China?

After investigation, the standard bow in ancient China should belong to compound bow. But this compound bow is a compound bow in the ancient sense. Not a modern pulley compound bow. In addition, the technology of straight bow is simpler than that of recurve bow, which is convenient for mass production. It is believed that the standard weapon in ancient China should be the straight-drawn compound bow. Here is some information. In ancient China, not only the requirements for bow-making materials were very strict, but also the specific technological steps were specified in detail. "It is necessary to take six materials at the right time, and all six materials are gathered together, and the skillful ones are harmonious." Analyze the bow shaft in winter, cure the angle in spring, cure the tendons in summer, collect materials in autumn, put the bow arm in the bow box in winter, and repair the appearance in extremely cold winter. In winter, the wood texture of the bow shaft is naturally smooth and delicate; Curing horns in spring naturally moistens and softens; Treating tendons in summer will naturally not be entangled; Autumn harvest, white and tight; If the bow is fixed in winter, it will not deform; When it is extremely cold in winter, the glue and paint are completely dry, and the appearance can be repaired. Install bowstring in spring and hide it for another year before using it. The above complicated process takes two to three years. In the bow-making workshop, because all the work can be staggered and streamlined, there will be batches of finished products every year, but as far as a bow is concerned, its working hours cannot be shortened. The manufacture of compound bow represents the peak of ancient bow making, and the detailed record of compound bow manufacturing in the world was first seen in Flower King Gong Ji. In the following two thousand years, the manufacturing technology of compound bows in China, or Asia, has not changed substantially compared with the examination records. Due to the different materials of bows used around the world during this period, the ways of pulling bows are very different in areas where single bows are mainly used and areas where compound bows have been widely used. Namely Mediterranean shooting and Mongolian (China) shooting. Europe has a long bow because of the poor elasticity of single bow and the low ratio of bow length to bow body length, while China's compound bow is just the opposite, with a high ratio of bow length to bow body length. When the bow is full, the finger bow forms an acute angle with the bowstring, and the fingers will be accumulated by the Mediterranean bow method. Therefore, the bow-pulling method in China is to use a thumb (with a hoop) to pull the string, and the index finger and middle finger press the thumb, while the single bow in Europe can be pulled with more fingers because of its large angle. Moreover, using the ring as protection is one of the signs of using the compound bow. China is also the earliest ring in the world. It was unearthed from the remains of Fuhao's tomb in Shang Dynasty and recorded in The Book of Songs. But China also has recurve bow in its ancient crafts. Juyuan Bow and Arrow Shop is one of the 17 bow and arrow shops in Beijing Dongsi Street Bow and Arrow Institute in the late Qing Dynasty, and it is the only bow and arrow shop in Beijing that completely retains the traditional craftsmanship. "Juyuan" bow is a traditional recurve bow, in which buffalo horn, bamboo, beef tendon and other materials are bonded together with glue made from pigskin. Its shape belongs to Manchu bow in Qing dynasty, and it has the characteristics of slightly larger bow.
