Case Review
Original writing · hindsight review · anchored in known history, viewed through chart structure
Yi (乙) Wood is the Wood of flowers and grasses, signifying growth and pioneering, with Indirect Wealth and Rob Wealth revealed in the year and month and Earth appearing three times. Looking back on the life of Li Siguang, founder of geology in the People’s Republic: using “geomechanics” to search for oil, refuting the theory that “China is oil-poor,” and the discovery of the Daqing oil field mirror the pragmatic prospecting of Indirect Wealth and the weighty empirical evidence of Earth.
Rob Wealth signifies competition and collaboration in tackling scientific problems. Water generates Wood (Hai 亥 Water); his choice to return from study abroad and serve his country is a footnote to “gaining Water.” Earth carries Wood, and his scientific spirit of “searching for oil at its source” can be observed in hindsight through the structure of “thick Earth nurturing Wood.”
This is a cultural retrospective at the level of three pillars, not a fatalistic judgment.
