Different from the usual tetraquark assignment to charged and charmoniumlike structures, in this letter we propose a universal non-resonant explanation to decode these ’s, which is based on a special dynamical behavior of . Our study shows that and are only the reflection from the P-wave charmed meson involved in . Obviously, the present work provides a unique perspective, which can be examined by future experiments like BESIII and BelleII.
