We observed three high-mass star-forming regions in the G10.3 Complex with the Australia Telescope Compact Array, combining with the complementary MALT90 data, to study the star formation activities in this region. These regions, i.e. G10.3E, G10.3M and G10.3W, are in different evolutionary stages and are located within the same large-scale environment, which allows us to study rotation and outflows as well as chemical properties in an evolutionary sense. While we find multiple millimeter continuum sources toward all regions, these three sub-regions exhibit different dynamical and chemical properties, which indicate that they are in different evolutionary stages.Even within each subregion, massive cores of different ages are found.
