What to do over Lunar New Year in Vietnam (Hanoi)?

Howdy folks, I will be in Vietnam (Hanoi) for about 10 days over the upcoming Lunar New Year (mid-to-end January 2020). Most of the time will be spent with family but I wonder if there is anything else to do there outside of the typical stuff like flower markets?

I heard the city will be super quiet during this period as many people return to the countryside for the Lunar New Year celebrations. If you have been in Vietnam (specifically Hanoi) over the Lunar New Year, I would like to get your feedback on things to do and places to go. I love my family and will no doubt spend a good chunk of time with them but I don't travel half way around the world just to sit at home and get wasted

Thank you all and Merry Christmas!
