We study the physical properties and 3D distribution of molecular clouds (MCs) toward the Cygnus region using the MWISP CO survey and Gaia DR3 data. Based on Gaussian decomposition and clustering for 13 CO lines, over 70% of the fluxes are recovered. With the identification result of 13 CO structure...
