Two roosters married

Hi, I have researched several sites and also many people talking about the same zodiac can not be married. However we have been in love and married for more than 5 years and have 2 sons, 1st boy in year of dragon and 2nd boy is horse.
During 5 years, good and bad thing happens but we are in harmony so far, just business life is not so good.
So my question is: "is there any way that we could change our fortune to be luckier and last long our love till end of the world?"

Thank you for your help
Cheers!
