Abstract: The origin of cosmic rays is a century-long mystery of astroparticle physics. Precise measurements of the energy spectra and anisotropies of those high-energy particles are the key to understand the origin of cosmic rays and their propagation in the Milky Way. The Dark Matter Particle Explorer (DAMPE) and the Large High Altitude Air Shower Observatory (LHAASO) offer us a very good opportunity to uncover the mystery of cosmic rays, via their unprecedented precision and wide energy coverage of cosmic ray measurements. New measurements of cosmic ray spectra by DAMPE and observations of a series of ultra-high energy gamma-ray sources by LHAASO shed new light on the understanding of physics of cosmic rays. This talk will introduce recent results from DAMPE and LHAASO, and discuss their implications.
