Women, I am the greatest >;>; Homepage www.1bw.org
(Note: The phrase "女人我最大" is a bit unusual and this translation takes it at face value. Depending on context, it might be adjusted for natural English expression.)
For a more natural English interpretation, it could also be translated as:
"I matter most among women" or "I am the greatest as a woman."
Let me know if you'd like a different interpretation based on specific context.
