“…The situation of the structure around 6.6 GeV is similar to X(6900), while another structure around 7.2 GeV can possibly be explained as a molecular state, because the energy is near the thresholds of η c (2S)η c (2S) and ψ(2S)ψ(2S). In order to understand the structure and properties of the fully charm tetraquark states, diquark-antidiquark configuration [24,81,432,434,[440][441][442][443][444][445][446][447][448][449][450][451][452][453][454], threshold effect [436,[455][456][457][458][459][460][461], color octet configuration [462,463], Higgs-like boson [464], and hybrid state [465] were proposed in various theoretical frameworks, in which the diquark-antidiquark configuration is the most popular one. In this subsection, we mainly concentrate on the work related to the diquarkantidiquark picture and the color octet configuration explanation.…”

According to the classification of the quark model, the hadrons going beyond three-quark baryon and quark-antiquark meson pictures are called exotic hadrons. Many new hadrons have been observed since 2003, some of which exhibit exotic behaviors. There are a lot of excellent review articles on exotic hadrons available so far; the present article tries to focus on the recent experimental and theoretical progress on the exotic states from the perspective of the quark model. Although lattice quantum chromodynamics may give the final answer of the problem, the phenomenological models are still powerful tools to explore the exotic states and to provide insight on the phenomenology of hadrons. The spatial and color structures of multiquark states and the channel coupling calculation are emphasized through reviewing some bound states, molecular and color structure resonances. Finally, the unquench effects of some exotic states are reviewed. With the accumulation of experimental data on multiquark states and inspiration of underlying theory developments, more reasonable phenomenological models incorporating multi-body interactions and high Fock components to unify the description of normal hadrons and exotic hadrons are expectable.
