CP287729277CN not delivered yet

hello,

My package was sent more as a month ago. The last date on track and trace of number CP287729277CN says
2014-01-28 12:47 上海国际 20110600 Departure from outward office of exchange. Normally i receive my package within 20 days. Can anyone tell me if there is some delay? Is this delay from china? is my package still in china?
I really feel powerless in this situation and my clients are pushing me. Can anyone tell me what to do?
