Affected by the TWC strength evolution and sea level rise, their contributions changed with time. There are five stages. Their contribution became lower during 6.5~3.0 ka B.P. and 2.0~0.7 ka B.P., yle="mso-spacerun: yes"> corresponding to the temporally weakening of TWC in the northern East China Sea and southwestern place w:st="on">Japan ype w:st="on">Sea ype> place>.
