  We explain the main idea of the chiral doublers scenario, originating from
simultaneous constraints of chiral symmetry and of heavy quark spin symmetry on
effective theories of heavy-light hadrons. In particular we discuss chiral
doublers for mesons, chiral doublers for excited mesons, chiral doublers for
baryons and chiral doublers for excited baryons. We point out the arguments why
new states D_s(2317) and D_s(2457) might be viewed as chiral doublers of D_s
and D_s^*. Then we comment on non-strange mesons D_0(2308) and D_1'(2427)
observed by Belle and Focus, and on Theta_c(3099) signal observed by H1.
Finally, we point out that very recent discovery by SELEX of D_s(2632), if
confirmed by other experiments and if spin-parity of this state is 1^-, may be
interpreted as a signal for chiral doubler of D_{s1}(2536). Such an
identification implies another narrow, spin-parity 2^- D_s state ca 37 MeV
above the new 1^-, corresponding to chiral partner of D_{s2}.
