2、玑字起名忌讳与同韵母ī或同声调阴平的字起名，这样读起拗口，没有节奏感;

3、玑字起名忌讳与先祖长辈同字，如果先祖名字中带有玑字，晚辈忌讳用玑字起名。

常见问题

如何查看五行缺什么？

  • 首先要谨记，五行不是缺什么就补什么，要看五行喜用什么。易经起名网的五行计算方式，是以五行含量计算的，不是按照五行个数计算的。五行含量可以保留到小数点后两位，五行个数只能保留到整数位。五行含量讲的是平衡，并且五行含量是以同类、异类成组对应看的，要让同类五行含量与异类五行含量保持平衡，后选出实际的五行喜用。

起名不满意？

  • 起名网提供的在线智能起名服务，给您选取的名字都是按照五行维度给您推荐的名字。起名不满意率几乎很低，原因是提供的需求不明确、追求高分造成的。取名讲究各个维度都符合，而不是追求分数，并不是分数高的名字，就一定适合您的宝宝使用，因为每个宝宝的出生时间都不一样。如果您有任何疑问，联系我们专职售后客服，为您合理解决您所提出的问题。
