This drama it is so well done on all levels, the performance of all professionals it is so outstanding, that the end result for me was that I could take it in only in small doses. No binge watching for me. This is something to be savoured. But also something to be weary of: the subject matter is dark and its rendering touches one deeply. It reminded me my first watching of Stanley Kubrick's adaptation of "The Shining", with Jack Nicholson in the leading role. I was literally hiding behind the door frame and looked at the TV with one eye only, ready to take refuge behind the wall. I am a grown up now, no hiding behind walls for me. Just pretending to have chores to do, so that I can take in, in small doses, this beautifully crafted Chinese series. Also, among the great cast all around, it was great for me to recognize actress Liu Lin whom I first spotted in a support role in "The Story of Minglan" series, of 2018. There, she and many other so called support role actors, delivered to the hilt, to the point that there were more "main role" performances than the casting presumed to be.
