LY504935957CN is tracking number. Is there a way to find out the weight of this package being sent to me? Or how large or small it is?

I have a problem with RM351720821HK. In my russian post tracking service i saw that this parcel weight 68gramms but all items in this parcel should weight at least 633 gramms. I think that the service that was in charge of sending my parcel cheated and didn't send the whole order. Can you give me details about the exact weight of my order?

Hello sir / madame,

More than a month ago a package was sent from the Netherlands to Qingdao, Chengyang by the name Sharon de Rooij (my girlfriend). PostNL sent the package to China and according their tracking system it was sent to the location. Because nobody was home the package was not delivered. Since then (7th of April 2016) the package is lost. I really want to find my package.

I believe Sharon de Rooij is not that hard to find as it is a rare name in Qingdao. The number of the package is: CC051856242NL. Weight: 1,76kg. Volume: 9,21L.

I hope you can help me.

Kind regards,

Vincent de Jong
