What was the song empire was like during healthier times and the bad times?

but it grew weak n was attacked by enemies from north. it lost most of its northern territories n ruled only southern china. it was called the "south song" dynasty. due to limited resources, time was tough. it had to maintain a large army to protect against the north which required heavy taxation of ppl.
