I am so impressed by this series that is impressively well well written and acted.
Never have I watched one that can so effortlessly and so often switch between good humour in one scene to being deep and emmotional in the next then back again.
Acting from the whole catst was excellent and I hope the actor playing the lead has won an award for his brilliant perfomance of the surly and stupid Yi Yong who does what's right.
For much of the series it's basically a complete story per episode but for the last 3 it's so well done how there's a common thread that only becomes fully apparent in the amazing finale with its action, surpises and tears as well as the trusty humour.
To be honest there were some things I found confusing which wouldn't have been helped by the engllish subtitles on iQiyi that too often flashed up too quickly to read.
