  We perform a systematic study on the interactions of the
$\Sigma_c^{(*)}D^{(*)}$ systems within the framework of chiral effective field
theory. We introduce the contact term, one-pion-exchange and two-pion-exchange
contributions to describe the short-, long-, and intermediate-range
interactions. The low energy constants of the $\Sigma_c^{(*)}D^{(*)}$ systems
are estimated from the $N\bar{N}$ scattering data by introducing a quark level
Lagrangian. With three solutions of LECs, all the $\Sigma_c^{(*)}D^{(*)}$
systems with isospin $I=1/2$ can form bound states, in which different inputs
of LECs may lead to distinguishable mass spectra. In addition, we also
investigate the interactions of the charmed-bottom
$\Sigma_c^{(*)}\bar{B}^{(*)}$, $\Sigma_b^{(*)}D^{(*)}$, and
$\Sigma_b^{(*)}\bar{B}^{(*)}$ systems. Among the obtained bound states, the
bindings become deeper when the reduced masses of the corresponding systems are
heavier.
