Can you explain me about my 4 pillars and 5 elements and it's significant.

Four pillars: year of Xinwei, month of Renchen, day of Jiwei and time of Jiawu.
Your four pillars indicate that you are kind and polite to other people. You may not make success in your early time. However, you will be successful in your late life. And you are not suggested to get married early. Otherwise, you two may have too many fights and quarrels. Although you have many children, just half of them can make success. By the way, your oldest son may encounter great danger.

Your do not lack a certain element. the relationship between these five elements is compatible. And fire is your lucky element.
