Can anyone recommend online texts, courses, academic papers or other source that goes over ancient chinese architecture/construction civil engineering from a practical setting spanning any point of time starting from the warring states to the end of the ming dynasty? From all scales, from individual building designs to city layouts. Said sources don't have to be super credible or well-vetted, as this is not for academic or employment purposes.

If you just tell me about it in a comment that's ok too!

I want to understand the architectural principles, designs, and processes that were used from a practical standpoint as opposed to the more commonly seen artistic standpoint (obviously the two may intertwine). If they are easy to understand for someone with no background in architecture/engineering whatsoever it would be great.

I know this seems open ended the rules recommend you to do your own research, but I didn't have much luck on google or google scholar :(. The intended use is just in fictional writing, hence the relatively broad area of the timeline.

Thanks so much in advance
