This paper argues that Chinese value of "He" (13158_2009_BF03168877_f1.jpg) or Harmony can contribute to understanding sustainable development as the concept encompasses the relationships between human and nature (ecological sustainability), and between human and human (social and economic sustainability). This interconnectedness with the "other" has its historical roots in ancient Chinese philosophy. This paper reports the practice of an international education provider in Hong Kong which embraces the Chinese value of "He" in its educational philosophy. A case example of how to use an integrated approach on education for sustainable development in early childhood setting is described.
