See this output, seems like the parcel got stuck in a loop. 😕
Could you please check? Thanks.

parcel looping in Guangzhou is very bad sign which normally means it can not pass customs scan. You can wait one more week and see what happens. If it is still Guangzhou, you should open dispute for lost parcel.

Thanks. I'll wait for another week and see.
