Hey, my Order has not been updated since 12 days, its stuck in "Guangzhou City, leaving the Guangzhou International Center, the next stop, Guangzhou International Exchange Station (transit)". What's going on?

Tracking number : LZ320446166CN

My package send with e-Packet got stuck on very weird status " leave the Guangzhou International Exchange Station, the next stop Guangzhou International Center" normally package takes only a day to get from one place to other in Guangzhou but now my package is stuck for a week and didn't even left China yet.
How is it possible? Did it got lost?
