Why is the history of more than 60 years before the Yellow turban insurrectionary in the Eastern Han Dynasty rarely put on the screen?

The main reason is that the Eastern Han Dynasty is too far away from now, so there are not many novels describing this period, and even fewer can be used as scripts for film and television dramas. In addition, this is related to the cost of film and television dramas. Now most of them are historical dramas of Ming and Qing dynasties, so there are many costume props in these periods, and the cost of renting these costume props for shooting will be lower. Costume props were definitely lacking in the Eastern Han Dynasty, so the cost would be higher. This is also one.
