请将下面这段话翻译成英文：

孔雀舞(peacock dance)是傣族(Dai ethnic group)最广泛流传的古代舞蹈之一，同时也是傣族最受喜爱的舞蹈。对傣族来说，孔雀象征着好运、幸福、美丽和诚实，所以跳孔雀舞是为了歌颂美好的生活，表达对幸福生活的美好的祝愿。孔雀舞主要在傣历的新年-泼水节（the Water-splashing Festival)、关门节(the Gate Closing Festival)、开门节(the Gate Opening Festival)和一些重要的宗教活动上表演。他们通过跳优雅的孔雀舞来祈求和平与幸福。

参考翻译:

1.孔雀舞是傣族最广泛流传的古代舞蹈之一：“最广泛流传的”可用the most wide-spread表示，spread意为“传播”，wide-spread意为“广泛传播的”；“傣族”可译为Dai ethnic group。

2.对傣族来说，孔雀象征着好运、幸福、美丽和诚实：“对傣族族来说"可译为to the Dai people,因上文有“傣族”的全称，故此处可以简写，也可译为for the Dai people; “象征着”可以理解为“是…的象征”，故可以用be a symbol of：..来表示。
