The East Wind is an essential component in Wu & Shu kingdoms’ joint military operation to destroy the superpower Wei kingdom’s war machine.
The East Wind could be both tangible and intangible, either detectable or undetectable.
According to Song Dynasty I Ching master Shao Kangjie’s Book of Huangji Jingshi (皇极经世书), a book about the past and future of our universe, this world is to enter the last stage in the current Big Cosmic Circle in less than 2 years, which will be dictated by the agent for Fire, while Fire energizes the development of culture. By 2024 we shall be able to have a glimpse of a higher and better human civilization slowly and gradually emerging from the far horizon to approach this chaotic jungle world.
Fire certainly needs wind to deliver oxygen for burning, and the East Wind brings the freshest air.
