According to a draft by the Guangzhou Public Security Bureau, during the Asian Games, all buyers of kitchen knives and large fruit knives will have to register with their National ID. The registration process also requires that the purpose of the purchase must be entered. Some parts of Guangzhou City have been monitoring the trail of this new policy for some time now. Sellers must comply with the policy as well. Only those authorized by the government can sell kitchen knives. The Public Security Bureau has been sending officers to do random inspections of seller sites. How the knives are carried is also regulated. When appearing in public places, knife owners are required to wrap the knives so that they “cannot hurt other people.”
