2 months ago, I experienced typhoon level 1 in Hong Kong whilst heading to the top of Lantau Hill. Then the next day in HK, I experienced typhoon level 3 where most of the shops there will close early.
What happened today IMHO is probably typhoon level 4-5, the wind is so blardy strong that it damaged & shattered one of the glass doors of my office building.
For those who are planning to leave the office soon, stay till the wind calms down ya. Those who are rushing somewhere, just be safe.
