Hello！ My package LJ042017660CN first went from Zhuhai to Guangzhou, was stuck there for a week. Then it again appeared in Zhuhai and got stuck again. Based on my previous experience, package should have gone through customs in Guangzhou, not returned back. Does anybody know what can be the reason？

I placed an order almost a month ago and it seems (according to Cainiao and 17Track) that my package is stuck in a loop with no chance of being cleared or at least sent back to the seller.
I've counted 7 times of it being returned ("remarks: security check returned") to a previous point in Beijing. It's going back and forth between Beijing International Mail Processing Center and Beijing International Mail Exchange Station.
Is there anything I can do from my end?
