Hello, I have USPS First Class package (Tracking #: UA930837154US) that left Georgia in the USA, and arrived in Beijing in November 1st, 2020. Tracking only shows the following: "Your item departed a transfer airport in CAPITAL, BEIJING, CHINA on November 1, 2020 at 11:49 am. The item is currently in transit to the destination." USPS doesn't have any additional information. The recipient is a customer and has been contacting us about the order as it has not shown up. Thank you for your help!

A package sent t to me from the US has been stuck in Beijing. I am wondering if ai need to pay duty, or it's just stuck.

Hello
in 2020 in October (10.2021).
I sent 3 parcels from Russia to Cambodia. In November (11.2020), the parcels arrived in China. Soon they returned one package. And two parcels were detained (北京市, 进口 互换 局 留存) by Beijing, left by the Bureau of Import Exchange.
The latest information for November (11.2020) that they are there. I wrote a response letter to Russia. I wrote to the post office of Russia, China, Cambodia. Nobody wants to do anything. What should I do ? At the Russian post office, I requested a return of the parcels. what should I do? Help
