Heroes run against crowd, toward the danger

One sentence in the Newseum in Washington has stuck in my mind since a trip last summer: When you see people run against the crowd toward the danger, they are probably firefighters, police or journalists.

I think this rings most true for the firefighters. Whenever and wherever disasters happen-9/11 in New York 14 years ago or the explosion in Tianjin on Wednesday night - it is always the firefighters who take the lead to run to the very center, saving lives by risking their own.

I cried today near the explosion site, not because of the smoke from the ongoing fire but because of a short message a firefighter sent to a trusted friend that went viral online. It reads: "If I cannot make it, my father is your father; and please remember to sweep my mother's tomb."
