Can Anyone Track My Product At All?

I ordered my product from Aliexpress. I bought it on Jan 17th, 2014 and it was shipped Jan 19th, 2014. My tracking number is RB312608896CN. Please, I really need to know what is going on with my package and why hasn't it been tracked already. I asked the merchant and said because of Chinese New Year, it got delayed. I just want to know when will it get here. I live in Illinois.
