During the security check at China Railway Station and high-speed railway station, passengers don't have to take off their wigs, but they will be asked to take off their hats and other head items so that security personnel can check their heads. In addition, if the wig is too thick or too loose, it will be removed by the security personnel because the security machine cannot scan normally. Therefore, wigs can be brought into the high-speed rail, but if metal objects are detected on the wig piece during security inspection, they will still be required to take them out for inspection.
