Mariner - CNY cruise?

I was looking at cruises and noticed the Mariner has two sailings that look identical, but have different names.

They look exactly the same except one has "CNY" in the title. Does anybody know what CNY stands for, or if there's any significance to it being listed separately?

CNY = Chinese New Year.

It is super peak period, CNY. Cruises 2 or more weeks later should be selling for much less.

That makes a lot of sense. Also explains why the Feb 16th Quantum out of Shanghai is so much more expensive than the cruises on either end. Interestingly, the two cruises above are the same price
