Why didn't Emperor Kangxi broadcast it?

Because the plot changed history, the TV series was not broadcast.

"Emperor Kangxi" is a historical costume drama jointly produced by Alibaba Pictures and China Film Co., Ltd., which tells the legendary story of Kangxi's reorganization of internal dignitaries and the pacification of three transgressions. The play was completed as early as 20 17, and it is planned to be broadcast on CCTV 8. However, after the filming, the play was overstocked and was not broadcast.

The reason why this play can't be broadcast is because the plot has changed history and is suspected of misleading the audience. When making and broadcasting historical TV dramas, we should strictly abide by relevant laws and regulations, respect historical facts and avoid misleading the audience. If the story has problems such as tampering with history and distorting facts, it may be reviewed and rectified by relevant departments or even stopped broadcasting.
