We have observed CS (J=1–0/2–1) lines in a 60′×30′(1×b) area of the Galactic center region. There are two large-scale features with elliptical shape in the position–velocity maps, which suggest shell–like structures in the region. One is the ring with a radius of ~40 pc in the positive galactic latitude region and another is the shell with a radius of ~20 pc in the negative galactic longitude region. These could be due to suggest star bursts occurred in the Galactic center region.
