The wording used in the name has nothing to do with whether you were born during the day or at night. It has nothing to do with zodiac sign.
The five elements of the name can only be determined by analyzing the likes and taboos of the eight characters. As for which words can be used and which words cannot be used, it is necessary to analyze the horoscope, fortune and other information to finally determine.
According to the birth time you gave
The eight characters are: Renchen Jiyoujihaijiazi
The five elements are: water, earth, earth, metal, earth, water, wood, water
This horoscope and five elements lack fire. Fire is the god of the horoscope and can be added to the name.
It is advisable to choose a name with the five elements attributes of fire and earth. Avoid using characters whose attributes are gold, water, and wood.
Purely judging from the five-element attributes of the characters used, the character "Xu" belongs to wood and is a taboo god, so it should not be used.
