Abstract：

The D⁰-D⁰mixing at Belle in different modes with corresponding methods is reported in this paper, there is a clear evidence for non-zeroyD⁰mixing parameter, and the measurement of D⁰mixing parameterxis still a challenge. CP violation in the decays is not observed. Branching fractions of other charm decays are presented.
