Tv plays belong to the category of entertainment and business, and it is easier to attract everyone's attention and watch psychology by adding fictional plots. So as to make money. Otherwise, a lot of investment may go down the drain.

Don't look for real history from TV series, you can watch history books or documentaries.

If you want to know history, you'd better read historical records and never watch TV series. The TV series is the same as the historical records, and it is estimated that few people have seen it. The adaptation is also for watching, but what is too funny and deviates from history is not much better, and it is still worth the director's reflection. If you want to make a serious historical drama (except online novels), you must respect history and restore it at the same time.
