Hello!
I ordered from aliexpress an instrument and the first few days it was moving great, but after the Chinese new year, it has been stuck in the Jiaxing processing mail center for almost a month. The last known tracking info was that it was leaving the Jiaxing processing mail center and going to the same mail center. Has my package been stolen?

Tracking number is RY532778055CN

Can you help me locate my package? It seems like all bbn packages with tracking numbers starting with U get stuck at the secondary processing Center. Is there a phone number I can call? USPS can not locate this package. It is not in their system. The seller is not cooperating with me either. I need to locate the package at the processing center. Tracking #UJ548047589CN. Thanks!

Still waiting on my order with tracking number RV421990142CN
From May 25th til June 1st the same message and after that no information:
2020-06-01 09:07, Arrive at the Sita processing center
2020-05-29 16:53, Arrive at the Sita processing center
2020-05-27 17:51, Arrive at the Sita processing center
2020-05-25 14:14, Arrive at the Sita processing center
I contacted the seller for more information several times but they don't give me a proper answer and just copy and paste the same tracking information as above
Hope you can help!
