It is illegal to collect nunchakus in some countries, including Norway, Canada, Russia, Chile and Spain, where nunchakus are regarded as controlled weapons. In April 2006, Germany declared nunchakus an illegal weapon, claiming that it was a dangerous weapon that could strangle people. In Britain, the law once stipulated that nunchakus could only be legally held when they reached 18 years old, but it was stipulated that nunchakus could not be taken to public places, except the only way to the training ground in private places. However, in February 2065438 10, the judge ruled that nunchakus were offensive weapons and nunchakus were regulated by law in Britain. The reason why nunchakus became a controlled weapon is related to the Ninja Turtles in the 1990s. This generation learned about the power of nunchakus through TV programs very early, so when Britain introduced some fighting games, it changed nunchakus into nunchakus. In Hong Kong, wooden sticks and iron bars are controlled, but martial arts coaches can get permission to hold them, but rubber people can legally hold them. In Chinese mainland, nunchakus are not regulated by law for the time being, but carrying nunchakus may be considered dangerous and will be interfered by security personnel. Australian states have different laws, some are forbidden, some are not, and the United States is different, so you must pay attention to the local laws when holding weapons in these countries. With the liberalization of the law, it is more convenient to carry out nunchaku exercise in China, and even some schools have begun to pilot the teaching of nunchaku aerobics.
