Help my daughter find out what is missing in birthdays and five elements.

The date you said is in the solar calendar! Converted into the lunar calendar is August 27, Geng Yin, born at an early age.

Eight characters and five elements: Geng Yin

friend and mentor

Dinghai

Ding Wei! Five years of life, pine and cypress trees! The five elements are not lacking, but the "water" is a little less. Think about it when naming!
