       Abstract: The origin of Galactic cosmic-rays has remained one of the biggest puzzles in Astronomy for decades. The cosmic-ray population in the Galactic center can be indirectly probed in the radio, X-ray and gamma-ray windows. A unique type of source in the Galactic center, the radio/X-ray magnetic filaments, may serve as good probes for GeV/TeV electrons. Meanwhile, the X-ray/gamma-ray emission from molecular clouds in the inner hundreds of parsecs can put a tight constraint on the MeV-GeV, and even PeV cosmic-ray particles. In this talk,I am going to unfold the roles of the magnetic filaments and the molecular clouds in revealing the origin of cosmic-ray particles in the inner Galaxy. I will also introduce an exciting opportunity to put the first constraints on MeV-GeV cosmic-rays using the molecular cloud Sgr B2 in 2017
