Using the Purple Mountain Observatory Delingha (PMODLH) 13.7 m telescope, we report a 96-square-degree 12CO/13CO/C18O mapping observation toward the Galactic region of l = [139.75, 149.75]^deg, b = [-5.25, 5.25]^deg. The molecular structure of Local arm and Perseus arm are presented. Combining HI data and part of Outer arm results, we obtain that the warp structure of both atom and molecular gas is obvious, while the flare structure only presents in atom gas in this observing region. Besides, five filamentary giant molecular clouds on Perseus arm are identified. Among them, four are newly identified. Their relations with Milky Way large scale structure are discussed.
