Need self-defense, which weapons are not controlled?

Long-range flying weapons only include bows, recurve bow, traditional bows, pulley bows and various non-orbital aiming bow and arrow devices. As long as there is no blade at close range, such as nunchakus, eyebrow piercing sticks and throwing sticks, but there seems to be a length limit, which I don't quite understand. However, according to the law of our country, citizens can hold flying devices, but only bows other than crossbows can legally hold flying weapons, and the function of their arrows is specified, so they cannot be used indiscriminately. I don't know exactly. Anyway, there is one thing. According to the laws of China, bows and arrows other than crossbows can be used as legal flying weapons for citizens. But! It must be noted that all flying and deadly equipment should not be used on people, except under special circumstances.
