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.
