I think this is because the writers of Kangxi dynasty needed a hero and villain to set off the greatness of Kangxi. This is actually a very sharp contrast technique, and it is also the daily life of the TV series we watch every day, because the protagonists in the TV series we often watch have a very strong opponent. In order to highlight the aura of the protagonist, we all choose to maliciously vilify the supporting role, so that the audience will not look very dull.

However, I don't think we can compare history too seriously when watching TV series, otherwise it will be very sad in many cases, because most TV series will adapt history. Many TV dramas are not good at historical authenticity and some details that reflect the historical truth, and are often criticized, but some TV dramas pay more attention to details. I think it depends mainly on the screenwriter and what he wants to bring to the audience.

In fact, the real Zheng Jing in history is not as useless and stupid as Kangxi Dynasty, but a man with great wisdom, determination and skill. He can cultivate the island into an army with strong economic and military aspects and add a wall to Kangxi from time to time. I think it's useless to use two brushes, and it's not like what is described in the TV series.

The Taiwan Province Province was governed vividly, which allowed the people of Taiwan Province Province to enjoy the treatment of the Taiping era in the war-torn era. I don't think his skill is less than Zheng Chenggong's, but in the Kangxi Dynasty, it was probably to set off SHEN WOO of SHEN WOO, the wise man of Kangxi, who turned Zheng Jing into a buffoon who didn't know anything and did everything silly. This is quite different from history.
