24C in Shenzhen...I go out to play with my kids.

Plot the destruction of the human race.

Made a door snake for blocking the air draft from the entrance door. I play ukulele, I go to the gym to run (warm + breathable air).

I go to the beach because it's still warm here. 

Body heat, meet many fat meaty girls and ask them to help you stay warm.

since November, keeping up the electric oil heaters running over cold nights, helped a lot to not have super cold walls now, so continue using them every night, and sometimes at daytime, when really cold. each room have AC, but rarely use them, only when need quick heat for some short time. And, hot homemade soup and some booze helps too.
