  Recently, the LHAASO collaboration has observed the gamma rays of energies up
to ten TeV from the gamma-ray burst GRB221009A, which has stimulated the
community of astronomy, particle physics and astrophysics to propose various
possible interpretations. In this paper, we put forward a viable scenario that
neutrinos are produced together with TeV photons in the gamma-ray burst and
gradually decay into the axion-like particles, which are then converted into
gamma rays in the galactic magnetic fields. In such a scenario, the tension
between previous axion-like particle interpretations and the existing
observational constraints on the relevant coupling constant and mass can be
relaxed.
