The following thinking is my own regarding the current state of the restrictions and is in no way indicative of anything other than my personal thoughts on the matter.
There has been much said about the Chinese government and restrictions on how many episodes of costume, period and historical dramas may be aired on the channels per year, thus causing a huge bottleneck as they are only allowed 100 episodes total.
The concern has been that Chinese folks are possibly confusing what is fictional, mixed with the actual facts, in replacement of the actual history. That is to say, the faction/fiction/historical mix is confusing and now people are considering some of this "real".
What I am going to say here...is this is not the first, nor the only nation to have this problem.
And the solution is very simple really - around this site, you may see the placards at the start of many such dramas, stating that this is a fictional account that may have historical figures in it, or a logical and well-placed placard thus ENSURING no one views it as a strictly-historical account of events in the drama.
There ARE some strictly-historical dramas around...in several countries. These too may be earmarked as such, by such a placard at the start of every episode.
Korea, for one, has marked dramas in such a fashion - and cheerfully broadcast "Moonlight Drawn by Clouds", where a Prince doesn't die when he should and other features are clearly out of fact in history...so...all may enjoy the charming stars. No one thus mistakes this account as the facts of the matter.
If the perceived confusion on the part of the public is indeed the entire base of this matter, then the answer is simple, and thus the people may have their cake... and enjoy it without concern. Like the many other nations of the world, who flag the confusing dramas and then enjoy them.
Anyway - admittedly, I thought about it as my own personal ox, the love of the Chinese historical/costume/period dramas stands broadside to the goring here. But given also the high stakes for the government of the country, why would they not embrace a simple, yet elegant solution?
Oddly too, this might solve the "time travel" dilemma as well - a placard stating that no such thing exists, and that it is merely a fantasy...may solve this one too?
I guess...with such simple solutions, the question is whether the government wishes to solve it, is motivated to put these dramas on air or not. Is it more beneficial to move them to other means of broadcast for the government would be another good question. Perhaps there is more to the 100 episode restriction than meets the eye here, perhaps it is meant to encourage other programming be placed in higher regard.
