This shows people's anxiety... I guess. Drugstores do not have toilet rolls, tissue paper....Supermarket do not have foods.... breads... rice.... just in case, I checked with rice shop... they are selling only rice.... they didn't have rice !
Don't panic, the most important thing is to help sending goods to those quake hit area.... gasoline also.
I saw people buying many instant noodles.... what are you gonna do with all those !?
Just buy what you need for a few days, not for months ! please.
