There is a saying about this word. Hanyu is also called "Hanyu", which is the jade buried in the mouth of the deceased. It is different from the gag of one of the "nine tricks", and some books also call it "tongue-holding". Folk believe that "the jade in the mouth of the dead" is related to death, so it is unlucky to name Han, so it is not good to be a name.
In addition, the five elements of the Chinese character Han belong to fire. If the names of people are prosperous in numerology, or if the eight-character joy is compatible with fire, then it is not appropriate to use the Chinese character Han to name them, which violates numerology and cannot achieve a balance in mission, thus affecting the fortune development of the names, which may hinder their career, wealth, marriage, health and other aspects. Among the five elements, water is like fire, and fire is like gold, which means that the eight-character joy is water or gold.
