When choosing a name, is there any explanation for the five lines between the characters in the name?

This requires five squares to match, not random spelling. Each word has a different meaning, and the strokes are also different

So the same pronunciation means different meanings, and the same meaning A name has different meanings depending on the year, month and day of its birth. For example, if the three characters are arranged in different orders, they may be mutually reinforcing or interfering with each other.
