RC509498136CN this tracking number showing only delivery to airport.(Beijing) no after details. why?

It's because China Post can't provide further update after your parcel left PRC. You should wait for your package patiently.

What is the meaning of PRC??

PRC is short for People's Republic of China.

Thanks for you answer. but i like to know why take too long?? last information Delivery to airport on 24/03/2014. no any info after that. thank you.

Lakshan, there are many factors. If the package was sent out of PRC, then it's Australia Post's responsibility to send the packages to you. If the parcel passes the customs successfully, then it comes to Australia Post. I suggest you visit the post office frequently.

thanks Ms. Kevin.... but why they send my parcel to Australia Post's ?? it came from Beijing-china. there is can send parcel directly. now 30 days have been passed.
