Even the greatest giants fear your technique.

Prerequisites: Wis 13, dwarf or gnome, defensive training racial trait, Earth Child Style, Earth Child Topple, Greater Trip, Improved Trip, Improved Unarmed Strike, Stunning Fist, Acrobatics 9 ranks.

Benefit: You can trip a creature of the giant subtype no matter its size. While you are using Earth Child Style, when a prone creature of the giant subtype stands up and provokes an attack of opportunity from you, if you make an unarmed strike, you can declare you are making a Stunning Fist attempt after the attack hits. You gain a +4 bonus to the DC of any Stunning Fist effect you deliver in this way.

Normal: You can only trip opponents who are one size category larger than you.

Combat Trick (from the Combat Stamina feat)

Source Pathfinder Unchained pg. 118
You can spend 5 stamina points to use Stunning Fist without expending a normal use of Stunning Fist when a creature with the giant subtype provokes an attack of opportunity by standing up.
