Jumping rope is a sports game in which one or more people do various jumping movements on a circular rope. This game was called "Head Rope" in Tang Dynasty, "Jumping Rope" in Song Dynasty, "Jumping Hundred Ropes", "Jumping White Rope" and "Jumping Horse Rope" in Ming Dynasty and "Jumping Rope" in Qing Dynasty. Skipping rope, as an ancient folk entertainment of Han nationality, has been used every festival since the Southern Song Dynasty, and every household has to compete.

The origin of skipping rope: skipping rope has a long history. When Nu Wa "leads the rope in the mud and holds it by people", the rope will live with people. The ancients used ropes to keep records, and also tied harvested crops with ropes, or tied cattle and horses, tied prey and so on. Rope has become an important tool in human life. Therefore, skipping may have originated from primitive farming, hunting or military activities.

The 18th time in Jin Ping Mei, a novel of Ming Dynasty, the names "vault rope" and "jump hundred ropes" were used, both referring to skipping rope. But the "vault rope" gives us an inspiration to explore the origin of skipping rope, that is, the "vault rope" used in ancient wars. Maybe the ancients were inspired by military activities. In the military training of tripping and avoiding tripping, they changed riding to single skipping, which gradually evolved and eventually became various skipping activities.
