Blood Type Personality Knowledge Base · 血型性格知識庫

In East Asia (especially Japan and Korea), a popular belief — ketsueki-gata (血液型性格分類) — links the four ABO blood types (A, B, O, AB) to personality. LocalPapa’s sun-sign and Chinese-zodiac tools let you add your blood type for a combined sign × blood type / zodiac × blood type reading.

※ Blood-type personality theory is a popular cultural belief with no scientific basis — for entertainment only. / ※ 血型性格說（血液型性格分類）為流行文化說法，並無科學根據，僅供參考娛樂。

This is the static knowledge layer in Open Knowledge Format: stable, human- and agent-readable. The dynamic layer — combining your sign/zodiac with blood type — runs 100%% in the browser, with nothing uploaded.
