5. May I suggest you read this for Saudi Arabia:
http://track-chinapost.com/China_Post_Arrival_Time_Stat.php

6. Please be aware that the 3 parcels starting with the tracking number 03, you will not see anymore tracking for those parcels. It can only be track in China not in your country. For the parcel of Singapore, you could maybe track it on the Saudi Arabia Post site went it arrive in the country.

Hope this help.
