Happy New Year = 新年快乐 [xīn nián kuài lè]
Under the 2009 blanket, the sleeper’s feet stick out; the 2010 blanket has a new piece stitched on, long enough to cover them. That is a happy new year: 新年快乐.
新年快乐 (xīnnián kuàilè) means “Happy New Year.” 新年 is “new year” and 快乐 means “happy.” The same 快乐 is in 生日快乐 (shēngrì kuàilè), Happy Birthday.
新年快乐 works on January 1 and at the Lunar New Year. January 1 itself is 元旦 (Yuándàn); at the Lunar New Year people also say 春节快乐 (Chūnjié kuàilè) or 过年好 (guònián hǎo).
新年快乐！ — Xīnnián kuàilè! — Happy New Year!
祝你新年快乐。 — Zhù nǐ xīnnián kuàilè. — I wish you a happy New Year.
