Su Dingfang is an archer hero found in the Scenario Editor in Age of Empires II HD: The African Kingdoms.

In-game, he is represented by a Chu Ko Nu. Like other archers, he is affected by all upgrades that affect archers as well as any other bonuses that affect archer units. As a hero, he cannot be converted and can regenerate health.
