It is taboo to use uncommon words in names. Because names are for communication, otherwise, the name will lose its existence value. If some uncommon words are used when naming, which most people do not recognize, it will inevitably affect the communication between people. Today's era is the age of computers, and the Chinese characters stored in most computers are limited to commonly used characters. Using uncommon words in names will only make others' work more difficult. Although naming should avoid clichés and similarities, it cannot be done by using uncommon words.
