Hun and Po are two of the aspects of our soul complex. Hun is Yang and associated with Heaven. It is our moral compass, allows access to higher consciousness and creativity, it is our connection to Divine realm and the Dao. As you mentioned, after death, Hun ascends (returns) to Heaven. It enters the physical body at birth. Po is Yin and associated with Earth. It gives us life, awareness, instincts, desires, After death, Po fades with the decay of the physical body In ordinary unrefined folks Hun and Po remain separate and their leanings and tendencies pull the individual in opposite directions. This is a problem. I will continue in a following post. I need to do some chores, chop wood, carry water, etc

That works. That works too as a distinction between Hun and Po. I am going to try and keep my responses in laymen's terms, middle of the road. Not to be mistaken for the Middle School. What I post will be broad strokes and not representing any particular school. I will avoid using terms like 'cinnabar field' 'yellow court' etc I won't go into finer details or specific practice/meditations. You didn't mention other considerations beyond Hun and Po. So, will keep a narrow focus on those. But I will, imo, fully address your OP I am no expert. I am a fellow bum participating in a discussion.

It's a really good question. I will offer some words and also Symbolism that I feel speaks clearer than just words to illustrate the concept. Nedan's idea is to refine and integrate the Hun and Po as a central part of the process to achieve Spiritual Immortality and Physical Well Being. Hun and Po are fundamental components of the framework of the process, as well as goals. If you need more understanding about Hun and Po, I suggest a new thread You can think of Hun as the software and Po as the hardware. As a human being you should functionally integrate both. That's what Neidan does; refines the ntegration. There is much more can be said and I know other bums will chime in. I just wanted to give a brief response to your question. Imo the abstract aspect of it could be addressed more directly in a thread detailing what is Hun and Po.
