Query: On the Geometry Origin of Weak CP Phase   In this work, the postulation that weak CP phase originates in a certain
geometry, is further discussed. Some intrinsic and strict constraints on the
mixing angles, weak CP phase, and the Wolfenstein's parameters $\rho$ and
$\eta$ are given by present data and the postulation itself. Especially, we
predict $0.0076 \leq |V_{td}| \leq 0.0093, 74.9^o \leq \gamma \leq 75.7^o$ when
the corresponding inputs are at the $90% C. L.$. The comparison of the
predictions to the relevant experimental and theoretical results is listed. All
the predictions coincide with the present experimental results and theoretical
analysis very well.
