Bow string up and down:

1, winding

In order to save the bow force, the bow should be bent downward when not in use. Therefore, it should be wound before each use.

When winding, the bow piece is clamped between the legs, with one side of the bow tip abutting on the foot surface and the bow handle abutting on the other side of the knee joint, so that the string ear is put into the lower bow tip, and the upper bow tip is held by one hand, and the string ear is held by the other hand, and the hand holding the bow tip is pulled hard until the string is in place. This legal person is called "holding the moon" and can be used for bows with weak bow force.

Step 2 open the bow

There are two popular archery methods: Mediterranean archery and China archery, both of which have a long history and have withstood quite a lot of actual combat and competitive tests. Novices should shoot in the Mediterranean.

Pull the bowstring to the cheek position. This step is called tilting, because the bow usually has only one aiming point, so a fixed posture is especially important for hitting the target. Exactly where to pull your cheek varies from person to person, but once you form a certain posture, you should remember it so that you can do it next time. This step is best to seek professional teaching. Developing the wrong archery habit will not only affect the hit rate, but also affect the life and health of the bow.
