"Han" refers to vastness, while "Xuan" refers to warmth and brightness, both of which are left and right structures, which make it beautiful to write as a boy's name. And its five elements are water and fire respectively, which also conforms to the boy's eight-character numerology. Therefore, we can name the boy "Han Xuan", which is a good name. "Han" is taken from "Han Hai", which has a vast artistic conception, broad mind and lofty ambition, and has a beautiful meaning. With the word "Xuan", the whole name is auspicious, and it also has a bright future.
