This report investigates the associations between supernova remnants (SNRs), pulsar wind nebulae (PWNe), and molecular clouds (MCs), and their role in TeV gamma-ray emission. Based on a systematic CO survey, we reveal that a high proportion (~80%) of Galactic SNRs are associated with MCs. Separately, a statistical analysis of LHAASO TeV sources shows that PWNe and SNRs are major contributors,...
