既来之，则安之（既來之，則安之）　

◎ 既来之，则安之 jì lái zhī,zé ān zhī

[since we are here,we may as well stay and make the best of it;now that we have come,let us stay and take the rough with the smooth;now you are here,you‘d better stay;since this is so,it‘s better to accept it and enjoy it] 既已来此,那就随安于此

他果然既来之,则安之,我也只得因居之安,则资之深。——《儿女英雄传》
