Guangzhou has started security checks at all subway stations and ferry terminals, and at the Baiyun International Airport on Oct 28, two weeks before the Asian Games kicks off.

All luggage will undergo examinations through an X-ray machine, and passengers will be searched at random. Police dogs are also being deployed for detecting explosives, guns and even knives.

The security measures will last for nearly two months, until after the Guangzhou Asian Para Games on Dec 22.
