We present observations of the J=1-0 transition lines of ^12^CO, ^13^CO, and C^18^O toward the Galactic region of 153.60{deg}<=l<=156.50{deg} and 1.85{deg}<=b<=3.50{deg}, using the Purple Mountain Observatory 13.7m millimeter telescope. Based on the ^13^CO data, one main filament and five subfilaments are found together as a network structure in the velocity interval of [-42.5,-30.0]km/s. The kinematic distance of this molecular cloud is estimated to be ~4.5kpc. The median length, width, excitation temperature, and line mass of these filaments are ~49pc, ~2.9pc, ~8.9K, and ~39M_{sun}_/pc, respectively. The velocity structures along these filaments exhibit oscillatory patterns, which are likely caused by the fragmentation or accretion process along these filaments. The maximum accretion rate is estimated to be ~700M_{sun}_/pc. A total of ~162 ^13^CO clumps and ~103 young stellar objects are identified in this region. Most of the clumps are in gravitationally bound states. Three HII regions (G154.359+2.606, SH2-211, and SH2-212) are found to be located in the apexes of the filaments. Intense star-forming activity is found along the entire filamentary cloud. The observed results may help us to better understand the link between filaments and massive star formation.
