The several levels of characters in the "General Chinese Character Standard Table" refer to the frequency of use. At this stage, the 1988 character list is still implemented, and the corresponding "Xinhua Dictionary" and computer fonts are also increased or decreased accordingly. For example, there was no "域" in the font in the past. In fact, many place names used this word. It was only added later. Since there are unnecessary troubles with the same name and surname, then the characters that are not in the font will definitely cause all kinds of troubles as the police said. For example, if you apply for an ID card, even if it is difficult to refuse, you must at least use the system to create the characters. If it takes time, then other medical, banking, transaction, education, etc. will definitely be delayed, and maybe it cannot be done at all, because some of them are application systems (and fools machine).
