What are taught at schools in Taiwan.
Some math. More math. A little bit more math. And some math.
What could be done - a class trip to mainland, then trying to take a train there, with security check near ticket halls, security check when you approach station, security check when you show railway ticket, and security check when you enter the train again. Also, to get to the station, you used metro, with security check.
Then you can explain, that if people will continue to tease terrorists, they may visit, occasionally, with presents, and Taiwan government will SURELY overreact, and you’ll get the same amount of safety checks in Taiwan as well. Wanna? Me neither =)
