The origin of nunchakus, who is the founder?

Controversy, there are two controversies, one from China and the other from Japan. It is said that nunchakus were founded by Zhao Kuangyin in 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 sticks were short and long, which were specially used to sweep away the clues of the enemy, break the armour or hard weapons, and make them lose their fighting capacity. Later, this weapon spread from the south to the Philippines and from the east to Japan. Due to historical changes, nunchakus has been changed to its present appearance: the total length is 72CM, and for every 30CM saved, there is an iron chain or nylon rope in the middle, which is about 12CM long. Bruce Lee's two-section stick is a standard 72CM two-section stick, which is different from the traditional large and small panlong sticks. Japan believes that the prototype of nunchakus is an agricultural tool. It is used as a flail or a horse to chew. 13 or14th century, many people from China immigrated to Okinawa (an island near Japan). These China people mainly settled in Kumi Village. They are proficient in all kinds of martial arts. One of them is the use of weapons. They call this weapon "nunchakus" or "nunchakus". Japanese people are very interested in this kind of martial arts. A large number of Japanese went to Kumi village to learn this fascinating self-defense martial arts. The technology learned later was translated into their names by the Japanese, and the names of weapons were also changed. The Japanese began to call this weapon "nunchakus". They also changed the shape of nunchakus. The nunchakus in China are made up of two round sticks connected by a chain. The Japanese connected two octagonal sticks with a rope. This type of nunchakus has developed different styles. Source of answer: /view/475484.htm#3.
