Selecting the newly observed $\Xi_b(6227)^-$ by LHCb as a study example, wedecode its inner structure by giving the mass spectrum analysis and theinvestigation of its two-body strong decay behaviors. Our result indicates thatthe $\Xi_b(6227)^-$ is a good candidate of the $P$-wave $\Xi_b^{\prime}$ statewith $J^P=3/2^-$ or $5/2^-$. In addition, we further provide the information ofthe properties of the partners of the $\Xi_b(6227)^-$. These predicted statesinclude three $2S$ states and the remaining $1P$ states in the bottom-strangebaryon family. The calculated sizable Okubo-Zweig-Iizuka$-$allowed decay widthsof these partners show that the experimental search for them becomes possiblevia LHCb. We have a reason to believe that the present study can be treated asa start point for constructing the highly excited bottom baryon spectroscopy.
