i have 2 seperate tracking numbers becouse my shipment was sent seperately

the first track code i got is this one RC342341905CN at this moment when i track it it says status NULL location PVG

the second track code is RC340483295CN but when i enter it there are no statusses but i got the track code 16dec so it has to be somewhere right ?

can anyone help me with these orders this is my first time ordering something from so far away (im from holland)
