I places in Asia that have monsoon weather one typically walks UP a few steps before going down into a subway station (China/Taiwan/Hong Kong/etc)- for example this MTR entrance in Hong Kong:

This is a great solution to short term small floods, but wont protect you against longer term, or waist deep+ street flooding like we saw in Henan last week.

I’ve lived in Hong Kong for close to 10 years, and I never even thought about why almost every MTR entrance has a couple of steps up, only to go back down.

With something like this: https://commons.wikimedia.org/wiki/File:Exit_A,_Sino-Singapo... the intention is even clearer.

Yeah, thanks, I was actually looking for a pic of my favourite Shenzhen Science Museum entrance that has maybe 6 steps (and is a real pain to drag a suitcase up)

I noticed this in Chengdu and Taipei and wondered a few times, why go up just to go down. Thanks for explaining this!
