What have happened to my parcel? RA598236608CN

Dear friend hi i've expecting a parcel from 15/12/2013 from China and it still hasn't arrived.
By checking the tracking number i only get receiving information and nothing more.
Could you please check it out and let me know what have happened to my parcel?
Am i going to receive it or it got lost or returnedback to seller?
I would appreciated your help and reply.
