Once in Beijing a child fired one netcafe and many young people were killed.

(that is very sad to hear.)

Billy, in English we would say "set fire to" instead of "fired."

"Fired" is when your boss thinks you are not doing a good job and tells you not to come to work anymore.

My kids (4 and 5) are going to learn it.

They'll have a head start on the rest of the children when they're all forced to learn it in the camps. ;)

Makes you wonder if he was giving his"seal" of approval?
