The ALMA observations of the high mass star forming region G10.34-0.14 reveal the presence of three massive cores, each with complex organic molecules. The most massive of these cores, called G10.34 S1, exhibits high and low velocity jet/outflow in various thermal emission lines (CO, SiO, CH3OH, and HC3N) and is associated with water and Class I methanol masers. The G10.34 N core exhibits low velocity CO outflow and is associated with Class I and II methanol masers. The third core, called G10.34 S2, is deeply embedded and does not appear to have an associated outflow. Based on the characteristics of the jet/outflow and the complex organic molecules, the evolutionary stages of these three massive hot cores are discussed.
