Sorry if I come across a bit strong. I am a something of a history buff, and the liberty that some Chinese historical shows take is shocking to me. I am like you, curious about different interpretations of familiar events.
I know it's just fyi. I understand the frustration that one of your favorite parts of history is being stumped on by bad TV shows. Any kind of "YanYi" is pretty just entertainment show. Some are not too bad, some are just aweful. In recent years, these bad shows are just getting worse. I think "JunShiLiangMeng" is better than most. Characters looked normal rather than hair-dyed XiaoXianRou with no facial expressions.
