Large High Altitude Air Shower Observatory~(LHAASO) opens the window ofultra-high-energy~(UHE) photon detection, broadens the path of testing basicphysical concept such as Lorentz symmetry, and brings possibility of potentialhigh-energy physical phenomenon research such as photon decay and electrondecay. Currently, the UHE photons from LHAASO observation set strictconstraints on photon and electron Lorentz symmetry violation~(LV) effects. Toobtain a global impression of the photon-electron LV parameter plane, we make adetailed analysis for photon decay and electron decay. Our discussion gives thecorresponding decay thresholds and energy-momentum distributions in differentLV parameter configurations. We get corresponding constraints on photon LVparameter, electron LV parameter and the photon-electron LV parameter planefrom LHAASO observation. For the space allowed for LV effect, that is beyondrelativity, we also provide corresponding boundaries from LHAASO observation.
