Hello, can you help me to understand what happened? The code is RI513855072CN. It looks like it is bouncing between Guangzhou and Shenzhen. Why do they need to open it 2 times?

Thanks, I found this and it looks similar to my situation: http://track-chinapost.com/?page_id=242/china-post-forum-group1/china-post-discussion-forum14/parcel-sent-back-and-forth-between-guangzhou-and-shenzhen-thread9886

By checking it now it looks like he received the parcel, I'm confused 😕

probably the customs found the reject is a mistake and release the goods again. Anyway, good luck for you.
