春节快乐 春节=spring festival 快乐=happy chǘn jīé küàī lè

Hi： usually, we did not say ' Happy Spring Festival ' first , I mean : when Spring Festival is coming or has been coming ,we firstly say "guo nian hao" (过年好) or "gei ni bai nian le"(给你拜年了) And then we say "zhu ni xin nian yu kuai"(祝你新年愉快) "wan shi ru yi"(万事如意) or other beatific words.

新年好 xin1 nian2 hao3 but I always say "恭喜发财，红包拿来" (gong1 xi3 fa1 cai2, hong2 bao1 na2 lai2) :P

Hello John, They also often say : Gong Xi Fa Cai 恭喜发财 = Congratulations and be prosperous !

XIN CHUN KUAI LE !
