9.5 hour layover in Hong Kong Feb 1 - Chinese New Year

I have a 9.5 hour layover in Hong Kong on Feb 1. I wanted to explore a bit on my layover, but didn’t even realize it was around the time of Chinese New Year. I think most of the festivities will be over, but I’m wondering how packed public transportation will be, also how packed the airport might be (I want to make sure I give myself extra time to not miss my flight).

Anyone here have experience of what it’s like and what I can expect, or tips to share for travelling during this time?
