Can a room number be added to my package by China Post, to help specify a delivery location? The address is correct, I only need to add room 306, to make the shipping location more specific. Can this be done?

Hello,
I was wondering if you would be able to tell me the location and estimated delivery date for order LZ623866320CN. It has been saying flight arrival for over a week but does not say the location of where it arrived. Thank you.

Hi. I live in Canada tracking says delivery was done by China EMS e-packet. It says it’s been delivered on 2 different days but I’ve been here all week and no one was here. So can you please tell me where exactly it has been delivered? The exact location would be nice to know. And if you don’t have that information then I would like to know what the address for delivery was on the actual package, because On my sale receipt it is my address but I haven’t been able to find out what was actually written on the package. Seller isn’t getting back to me, go figure!!! I am beyond frustrated with all I’m of this as you guys make it extremely difficult to be able to get ahold of anyone that can speak English and provide the details. I would appreciate it if someone answered me this time, as no one did the first time I asked for help. Thank you
