Hà đồ Lạc thư

Definition
  1. Proper Noun:
    • The Hetu and the Luoshu: A foundational concept in ancient Chinese cosmology and philosophy, referring to two mystical diagrams said to have been revealed from the heavens. The "Hetu" (River Chart) was revealed by a dragon-horse emerging from the Yellow River. The "Luoshu" (Luo River Writing) was revealed by a divine turtle from the Luo River.
    • A symbolic system: These diagrams are traditionally considered the origin of the Eight Trigrams (Bát Quái) used in the I Ching (Book of Changes) and the Ninefold schema (Cửu Chương) associated with the magic square and Chinese numerology, forming the basis for much of East Asian metaphysical thought.
