Birth Time Verification

Zhang Yiming's birth date is checked as 1983-04-01. I did not find a reliable public birth time, so 16:00 is kept only as a candidate hour. The four pillars shown here are Gui Hai, Yi Mao, Ji Wei, Ren Shen; the reading gives more weight to the verified date and public life record.

Core Analysis

Zhang Yiming's chart is Gui Hai, Yi Mao, Ji Wei, Ren Shen. The Ji Earth day master is born in the Yi Mao month, so the reading starts with temperament, pressure, and the way talent is put to use.

The page focuses on Entrepreneurial Drive and Strategic Vision. The chart is read together with public life events: work, reputation, conflict, and turning points.

Because the birth time is not confirmed, the hour pillar stays as a candidate.
