▍If you encounter danger when taking public transport any one of these four items could save your life
A book : When you realize you are in danger immediately take the book or whatever item you are holding in your hands and throw it at the attacker to distract him, so you can get away
Backpack : If an individual with a knife approaches place the backpack over your chest and belly to protect your vital organs and back away
Umbrella : When faced with an attacker raise your umbrella and point the tip in his direction, retreating and waving the umbrella to protect yourself, while attempting to knock the attacker’s weapon out of his hand
Fire extinguisher : If there is a fire extinguisher nearby, aim it at the face of the attacker, press spray and take the chance to flee the scene
In the event of such an incident, immediately press the emergency intercom in an MRT carriage or emergency bell on a bus to alert the authorities
