At the beginning of piety, avoid using the name of the monarch, or the names of superiors, fathers and elders, as long as you avoid using the same words as these people's names. This is called "avoiding justice". After three kingdoms, it began to expand into a word with the same name or even sound, which was called "avoiding slander". Therefore, to answer this question, we must first understand this basic common sense. We can know that the ancient escape is not limited to avoiding the emperor's famous monarch, but also includes all kinds of private people who are devout. Ambiguity in a broad sense.
so what is taboo? In layman's terms, I don't want to say or hear something that may cause unpleasant misfortune. In essence, this form is mainly caused by folklore, and this embarrassment has existed more or less until now in some places. For example, in some places, the word "discrete" is used to mean "pear" is "round fruit", while "umbrella" means "firm vertical"; For example, people sailing on ships usually avoid "turning" and "sinking" and waiting.
In addition, the famous saying that "only state officials set fires, and people are not allowed to light them" is precisely because Tian Deng, a state official, claimed to avoid noise and ordered the state to call lights. . The list of lights on RMB warns: "Hongzhou Island was set on fire for three days." When people were shocked by this, they came to the ground and became classics. As for the specific forms and methods of avoiding phlegm, it is beyond the scope of this question.
The method is: to perform certain, standard, save, write, rename, lose pen, variant, read, song, fill, analyze, hyphenate, cover yellow ... and so on. Here, I won't give you detailed explanations and examples. It can be seen that the ancients really racked their brains and hollowed out their minds in order to show respect for their ancestors, respect for their ancestors and respect for respect. This is not only meaningless to deceive people, but also poses great unnecessary trouble for future generations to read historical materials.
