moi无法进行太多对象的布尔运算，因此最好不要使用孔洞进行布尔运算，而是将整个装饰复制一份，隐藏，并对整体进行布尔，删除多余部分，显示。
（Moi cannot perform Boolean operations on too many objects, so it is best not to use holes for Boolean operations. Instead, copy the entire decoration, hide one of them, and perform Boolean operations on the whole, delete the excess parts, and then display all.）
