How to answer or dodge when people ask about my salary?

Is better to keep to yourself unless is your close friends.

Just say you are not comfortable sharing, and laugh it off maybe? Nothing embassass about not wanting to share salary info lah.

Cheers.

If family members or relative asks me, I always say "enough to pay bill and survive la"

Be firm and polite to reject them. Salary is confidential and personal. You can say you are not comfortable in sharing and change to another topic.
Remember you are new to the dept and your colleagues cannot help you fight for higher pay. Only your boss can.
