look nicely at the bag..
gosh, it's really consider such a quite "BIG" hole..
oh my, its width is bout my last finger's size, i can put my finger into the hole.
and OMG, it's not as small as you can't see it. It's consider a BIG hole though, cause I can't imagine what kind of insect can bite it to such big hole. Cockroach? or RAT???
arrgghhh~~!!! got rat in my room!?!??
Of course, i thrown in at the end...
