We have carefully examined the XYZ states and find that Zb states are molecular and the compositeness are quantified. Using a more general parameterization than effective range expansion, we find that X(3872) can be either virtual states or bound states, which can reproduce experimental data equally well. At last we show the connection of the P-wave $B^*\pi$ interaction and X(5568) by using the chiral unitary approach.
