The GuangZhou Baiyun International Airport has recently enhanced its security check. Passengers from some flights will be required to undergo a stricter body check, which can include removing shoes and leather belts. Passengers demanded to open belongings will increase by 50 percent.

The airport authority reminds passengers not to bring contraband goods such as lighters, matches or lithium batteries. To avoid huge crowds and flight delays, the authorities have increased the current 25 security gates to 52.

Beijing and Shanghai airports have also concurrently implemented the level II security check. Level II security check was once operated during the 2008 Beijing Olympic Games and 2010 Shanghai Expo.
