People are inclined to believe some repeated false propaganda out of ignorance. As time passes, the truth will be exposed. However, the public would rather be absorbed in fictions than pursue the facts. Some historic dramas and novels have distorted facts for personal or political reasons. Therefore, lots of historic truth has been concealed for so long. Some figures have been defamed and some deified, which has prevented modern people from forming right opinions about those personages. So historic dramas and novels have deceived audiences and readers while they give people an enjoyable entertainment. Even people of higher education can hardly avoid the deception.
