Research on extra-solar planets is one of the hot topics in astronomy during recent years. We search for planets and brown dwarfs around the late G, K-type giants with the 2.16m telescope and high-resolution spectrograph in Xinglong, study the difference in chemical abundances and other aspects between stars with planetary systems and normal ones, so as to further understand the formation and evolution of planets.
