The year 200 is the Renwu year of the lunar calendar, and 6:50 in the morning belongs to Si hour. From this, the boy’s birth date can be calculated to be the day of Ding Si hour, Gengxu month, Wuchen day, Renwu year, and then according to the five elements of Renwu The child belongs to water and fire, Gengxu belongs to metal and earth, Wuchen belongs to earth and Dingsi belongs to fire. Therefore, if the child's five elements lack wood, then it is enough to have a word with the attribute of wood in the name. Then calculate the child's birthday based on his birth date. Shen is also wood, so in summary, children can use dragon + wood attribute characters or dragon + generation + wood attribute characters!
