By the way, can I pass the security check if I bring fitness equipment, nunchakus (wood or iron), arm strength devices, tensioners, dumbbells, etc?
It's hard to say. It depends on your luck. If it is caught by a difficult security inspector, it will basically be confiscated. I haven't met it, but many people around me have been confiscated. I really found it. Please explain to the security inspector patiently and have a good attitude. Bring relevant documents, such as Wushu Association membership card and award certificate.
