Abstract
The phenomena of quark mixing in weak interaction are described. The current experimental status of the mixing matrix, charm and beauty particle decays, and CP violations are reported. Future interesting experiments are pointed out, especially in the event that higher generations of quarks exist.

Here I would like to emphasize that the graphs given here include all strong interaction gluon clouds. They are not Feynman graphs. For example the graph recently given by J. Donoghue in Phys. Rev. (figure on the left below) actually is an exchange diagram, which can be easily seen if we redraw as on the right below.
For charm → PP, see Table 2.5, Ref. (2), and footnote (2) of Ref. (3); For charm → PV see Table 2.6, Ref. (2) and M. Gorn, Nucl. Phys. B191, (1981). X.Y.-Y. Li, S.-F. Tuan (to be submitted to Zeits für Physik C). For treatment of SUB(3) breaking and final-state-interaction, see next reference.
