What's New in 问易 Yi
1.9.13
September 25, 2026
Yi 1.9.13 adds two ways to begin: explore a perspective or work through one question. Save observations, connect them to matters you care about, and return to your own reflections. The home, Observe, Stories and introduction screens are clearer, with improved large-text layouts and library recovery after an update. The home yin-yang animation now resumes when you return. Cloud assistance, AI-point purchases and birth-chart calculation remain disabled. Yi supports classical-text study and decision reflection; it does not predict outcomes.
