With the help of a new technique ``SU(3) analysis\" and a new explanatory framework of the B(E2) anomaly, it was found that, the $B(E2;2_{1}^{+}\\rightarrow0_{1}^{+})$ anomaly really can exist. In this paper, we discuss the $B(E2;2_{1}^{+}\\rightarrow0_{1}^{+})$ anomaly in $^{166}$Os for the first time.
