Butcher Boy Ba Zi (八字) is a Chinese-metaphysics practice based in Singapore. We read Ba Zi, Zi Wei Dou Shu, Qi Men Dun Jia, Da Liu Ren, Feng Shui, and I Ching the way a butcher follows the grain — calmly, precisely, and without fear-selling. Readings are working sessions, not performances, each with a written summary. Free calculators at app.butcherboy.com.sg
