Li abundance derived for 378 G/K giant stars from Liu et al. (2014b) as a function of T_eff and log g (left and right panels). The empty circles and crosses correspond to Li values and upper limits, respectively, measured for the 378 giant stars. The measured values in this work for stars A and B are shown in blue and red, respectively, and the predicted values after a possible planetary ingestion in star A are shown in green.
