Today's hexagram:Di Huo Ming Yi（䷣）

The Book of Changesauxiliary word for ordinal numbersthirty-sixHexagram, up Kun (earth) and down Li (fire), the earth is covered with fire, and the light enters the earth.

Hexagram revelation:The fire is hidden beneath the earth, and the light is temporarily obscured, like the sun sinking into the western mountains, and the sky and earth are hazy.After a volcanic eruption, the lava cools and forms thick rock layers, and beneath the seemingly extinguished surface, magma continues to surge in underground currents. such“There is fire in the ground”The scene is just like the core image of the Mingyi hexagram: under the surface silence, the heat of life never dissipates.This hexagramThe image of "Mingyi" reveals the survival wisdom of "inner brightness and outer softness" - when light is trapped in darkness, it is necessary to protect the inner flame with a restrained attitude, such as King Wen's performance of the Book of Changes in captivity, and Jizi's feigned madness and adherence to the right path. Only by outwardly showing foolishness and inwardly observing clarity can we preserve our foundation in the darkest moments, waiting for the opportunity to break through the storm and thunder.

Insight into the world reveals philosophy, and the light eventually breaks through the darkness.

This event marks the first time that humans have achieved mobile exploration of extraterrestrial celestial bodies, promoting the leap of space exploration technology from fixed-point landing to mobile scientific exploration, laying the technical foundation for the development of unmanned lunar and Mars rovers in the future, and deepening human understanding of the geological structure of the moon. It is a milestone in the history of manned spaceflightAn important milestone from 'stopping' to 'exploring'.
