Ding Sinan Dayun Jiazi asked how the eight characters 12 and 13 were calculated. Please explain it in detail with the principle of four pillars and five elements.

1988-10-10, the 30th day of the eighth lunar month, with eight characters: Ding Si in the year of Chen Wunian and Ding Si in the year of Yin Na's big forest, five elements, five soils, two fires and one water, seven fires of the same kind and one water of different kinds. The five elements of the sun belong to the earth, and the fate is centered on the earth.

Full of fire and earth, it is a prosperous pattern. Mixing water with water in the moon is a big taboo. Non-water is wealth, extremely weak, and there is a struggle.

Universiade Jiazi, kill the Lord seven times, transport and raise to meet the wealth, counter the game, the Japanese Lord from strong to weak (but still can be a financial officer). Time flies, and the Star of Wealth is in charge, but the underground branch of Tatsumi doesn't carry it out. Therefore, the Japanese Lord has a blessing, but it is not a big blessing and cannot be forced.

Personal opinion, for reference only.
