Nunchakus originated in China.
Nunchaku has a long history, and its evolution process is accompanied by the needs of ancient wars. Its prototype is a sharp stick, which evolved from the flail of threshing farm tools. Flail is used to fight crops, and it has different names in different parts of China. Some areas in the south are called diaocha or tiaoche, and some areas in the north are called scraper and rotary hammer.
As the originator of nunchakus, flail was first born in ancient Egypt, with a history of about 3500 years. China's written records about flail first appeared in the Spring and Autumn Period more than 2,500 years ago, and later flail appeared in other parts of the world, but it appeared relatively late.
The earliest record of the pointed stick can be found in Mozi's The Art of War in the early Warring States Period. Inspired by the flail, Master Mozi invented Lian Ting, that is, the big-end stick, for the need of guarding the city in the war, which was recorded in Mozi's Sixteen Art of War, Mozi prepares the city gate and Mozi prepares the Russian Fu.
Mozi listed it as one of the main guarding devices of Beichengmen, and asked for "two-step connection" in the city. "Mo Zi Bei Fu" said: "It is two feet long, six inches big, and two feet long."
The so-called stiffness here refers to the stiff tip section, and the cable is the cable chain connecting the tip section and the handle section. Sharp sticks appeared in Europe in the middle Middle Ages and were mainly used for immediate combat. Southeast Asia and other regions were introduced from China in the Ming and Qing Dynasties. So nunchakus originated in ancient China.
It is said that nunchakus were invented by Zhao Kuangyin of Song Taizu, and were originally called Big Panlong Stick (also called Big Sweep in modern North) and Small Panlong Stick (Small Sweep).
However, at that time, the big panlong stick was short at one end and long at the other end, which was specially used to sweep away the enemy's clues and wear armored soldiers or hard weapons, making it lose its combat effectiveness. [This nunchaku, which is long and short, is also often called "the tip of the tiger's tail", belonging to rope weapons and soft weapons. Later, this weapon spread from the south to the Philippines and from the east to Japan.
There is also a saying that nunchakus originated from the "flail" farm tools used by ancient farmers on the threshing floor. According to research, it existed in ancient times hundreds of years ago.
