In relation to the Chinese New Year (or Spring Festival) I've heard different names, as you can see from what I just wrote.
In Chinese we have:
春節 / 春节 = Spring Festival
Chūn jié農曆新年 / 农历新年 = Chinese New Year
Nóng lì xīn nián
or simply (more general)
新年 = New Year
Apart from the last one, which I doubt is the most used when referring specifically to the Chinese New Year, which one is the most common expression in China? And are these the only ones?
