1990 What's the best floor to buy?

Hello, dear, I'm glad to answer your question. According to your situation, I think that people born in Geng Wunian (1990) belong to horses, and the five elements belong to gold, which is suitable for living on floors with mantissa 4 and 9, so people born in horses can choose the 4th, 9th,14th,19th, 24th and 29th floors. You can refer to my answer, dear. I hope my answer is helpful to you!
