Happy the Christmas day:是这样用英语说“圣诞快乐”吗?这样说是不是用词不当？

Happy Christmas! christmas happy happy christmas 与merry christmas区别 外国不用happy christmas happy christmas eve是什么意思? A happy christmas day happy christmas对吗 happy christmas 啥意思? Happy Christmas' dinner . 为什么说“Merry Christmas”不是“Happy Christmas”? 为什么是merry christmas而不是happy christmas merry christmas 为什么不说happy Christmas Happy Christmas Eve怎么回答 Merry Christmas & Happy New Year a Happy Christmas有错吗? just for you happy christmas Just for You HAPPY CHRISTMAS happy christmas my sweetheart是什么意思? Happy Christmas eve!请翻译
