We just heard about the number 4 in chinese. is bad luck for marriage? my birthday is 03/03/1954

Hey, you needn't worry too much. Four is an auspicious number to Chinese people becaues its pronunciation is similar to Si (Death). However, it has the similar pronunciation with Fa in musical notes. Fa means prosperity. So it depends on how you understand this number.

For you, 4 is neither a bad nor a good number. Your lucky numbers are 2, 3 and 7. There are two 3 in your birth date. I believe that it can bring good luck to you.

Thank you so much for ur reply! But we got married on 040404. What do you think of this numbers?

It doesn't matter how other people think of your wedding date. It really matters how you think. I bought an aparment on the 14th floor. Honestly, many people think 14th floor is not good. 14 can be pronounced Yao Si in Chinese, meaning "want to die". But I don't care. As I said, 4 can be pronounced as Fa. So 14 can be Yao Fa, meaning "I am going to be prosperous".
