Literally: olden times – condition – depend on – “sort of thing”
Alternately: Something remains as it was, without any development or progress. Unchanged… or even if it did change, not improved in any way as a result.
Notes: This is another compound of compounds: 旧態 is “the way things used to be,” while 依然 is “the way it was at the start.”
Replacing 態 with homophone 体, “body,” or replacing 依然 with homophone 以前, “before,” is considered an error.
