Sorry for late reply, and i don't have Chinese input here.
I cut two 6" round holes at the existing HVAC main pipe, so that I can add additional pipes and two registers at the basement, one at the roof, the other at the wall. You can actually see the pipe I added in one of the photos where I was working on the ceiling.
I also added 220V outlet at the basement, just in case I need electrical heater (220V) later on.
