Our RT models successfully reproduced the Mg II line profiles for all 33 galaxies, revealing a necessary condition for strong LyC leakage: high maximum clump outflow velocity ($v_{\\rm MgII,\\,max} \\gtrsim 390\\,\\rm km\\,s^{-1}$) and low total Mg II column density ($N_{\\rm MgII,\\,tot} \\lesssim 10^{14.3}\\,\\rm cm^{-2}$).
