请问板上老师
以下句子
He also learns that Cunegonde is in another city, to which
Candide immediately sets off for.
句中的to which该如何分析,不懂为什么要多一个to出来?
再者,若把to 移到句尾,完全一整个怪.烦请高手释疑
谢谢
注:完整段落如下
Candide arrives in Venice and learns his servant was robbed
and is now acting as a servant to another man. He also
learns that Cunegonde is in another city, to which Candide
immediately sets off for. Once there, he finds Cunegonde
as well as Pangloss and some other people he thought were
dead. Despite the fact that Cunegonde has grown ugly,
Candide's heart is true and he marries her.
