I notice that centrioles always exist in pair. May I know why?

Simplest answer - centrioles are the points of attachment of the fibers that pull apart the pairs of chromosomes - these are spindle fibers. Centrioles are in pairs because two separate points of attachment are required -> one for each daughter cell. Each daughter gets a copy of the duplicated chromosomes during mitosis.
