In this talk we address two topics: The first one is an empirical explanation in terms of a new state h1 of the peak in the K*0 K̄*0 invariant mass distribution close to threshold of this channel in the J/ψ → ηK*0 K̄*0 decay. The second one is a theoretical description of the isospin I = 1 Zc(3900) and Zc(4020) states in terms of molecular states of DD̄* + cc and D* D̄*.
