  LHCb has productive studies of quarkonia and $b$-hadrons which provide
essential inputs to study quantum chromodynamics (QCD). In this proceeding,
seven recent results are reported: the observation of a new excited $\Xi_b^0$
resonance in $\Xi_b^- \pi^+$ final states, the new excited $B_s^0$ state is
observed in $B^+ K^-$ mass spectrum, the first observation of suppressed
semileptonic $B_s^0 \rightarrow K^- \mu^+ \nu_{\mu}$ decay, the first
observation of the decay $B^0 \rightarrow D^0 \bar{D}^0 K^+ \pi^-$, the first
observation of the Cabibbo-suppressed decay $\Lambda_b^0 \rightarrow \chi_{c1}
p \pi^-$, the first observation of $\Lambda_b^0 \rightarrow \Lambda_c^+ K^+ K^-
\pi^-$ decay, and end this report with the first search for the doubly heavy
baryon $\Omega_{bc}^{0}$ and a search for $\Xi_{bc}^0$ baryon.
