Help!! Chinese(Big 5) Display Problem

I created a database to store articles. The content contains Chinese Big5 code. I can stored it in MySQL, but I have problem displaying the content. The Chinese coding become something like "???Ld". I am not sure this is the Chinese handling problem of MySQL, Linux server or programming. How can I solve it???
