| NKH have _not_ been joking around with the evacuation warnings

| speaking _very_ sternly: "Evacuate, _now_! ", "Seek shelter,
| _now_!, "Seek high ground, _now_! ", "Protect the life of

| That is standard protocol and has been iterated upon each time

|
| Nowadays they put up a _very_ strong act of sounding emotional

|
| That being said, I have seen some images of collapsed buildings

|
| Indeed. For those who do not know, new year celebrations

| entails visiting in-laws, parents, and grandparents (or
