The changes of R_AK, R_KCN values of the study sites (a) DLW3101, (b) MD12-3429, (c) ZHS-176 and (d) MD12-3432. p-values are almost all < 0.05 when |r| > 0.6; e Chinese cave δ¹⁸O (Cheng et al. 2016) and mid-month July insolation at 15°N (Berger and Loutre 1991); f LR04 δ¹⁸O stack (Lisiecki and Raymo 2005) and global eustatic sea level (Spratt and Lisiecki 2016). The fill colors of the R_AK line mark the relative distribution of Taiwan (red) and the Pearl River (blue). Gray bars highlight the intervals of maximum insolation.
