Internal proper-motion measurements of 6.7 GHz methanol masers can provide unique information about high-mass star-forming regions (HMSFRs). The source G320.23-0.28 is the best case where the methanol masers are parallel to a large-scale bi-lobed outflow traced by H_2, SiO, and EGO emissions in the east-west direction. Therefore, it appears that the G320.23-0.28 methanol maser spatially and physically trace the outflow ejected from a high-mass YSO in early evolutionary stage. We have accurately measured the spatial distribution of the G320.23-0.28 methanol maser using the LBA (Project: v292a), and that distribution exhibited a complex spatial distribution. By applying the bipolar outflow model of Moscadelli et al. (2000, 2005) to our observed distribution, we obtained maser-outflow axis and opening angles that were consistent with the large-scale outflow. We propose to carry out three-epoch observations of the 6.7 GHz methanol masers in G320.23-0.28 to measure their internal proper motions. This measurement will provide vital information about both the location of this maser with SFRs and studies of outflows at early evolutionary stages in HMSF.
