My husband is born january 24 1966. I went to a chinese temple here in the Philippines to ask his zodiac sign. The master told me that hes zodiac sign is snake but according to this article he's zodiac sign is Horse. Is that true? my zodiac sign is rooster and according to feng shui master we're compatible because he is snake. now if hes real zodiac is Horse, im worried to discover that our zodiac sign we're not compatible. i want know our zodiac sign compatibility? I was born Dec 14 1957. We are married for 23 years. If ever our zodiac signs are not compatible? What can i do about it?
