The sixty stem-branch pairs crossed: sounds, harmony, clash and element relation

采用的约定

The existing sixty-row dataset gives the sound element of EACH stem-branch; this table crosses them because people actually need to compare two years at once. The element relation is judged by the SOUND element, not by the element of the stem or branch, which is how most Vietnamese practitioners read it; some schools judge by the stem-branch element and then the answer differs. Three Harmony, Four Clash and Six Harm group by BRANCH and are independent of the sound element, so a pair can be in Three Harmony and element-clashing at once. The table does not rank pairs as good or bad; it says what the relation is and leaves the weighing to the reader.
