Stands for the Hong Kong Observatory. The sole worst part of the government that cares more about the economy than the citizen's well-being.
Their worst-doings include:
-Wrongly hoisted the tsunami warning at 2004
-Not hoisting the red rainstorm warning (rain more than 50mm per hour) or the typhoon (hurricanes in the Pacific area) signal no. 8 (gale or storm) before 8am frequently, making everyone's shoes, socks and trousers as disastrous as 1941
-Giving wrong estimates or blurry times when reporting typhoons, for example saying that No. 8 will be hoisted between midnight and morning, and ended up hoisting it in the middle of the day (I forgot)
The HKO still hasn't hoisted the No.8 typhoon signal... DLLMCH I need to go back to school despite it's raining dogshit outside...
