I have the same problem with you.
The seller not willing to help/ lazy to ask china post office of update the tracking.
What I do now is calling the post office centre on my country & trying to call china post office

Hi pedro,

It left China on September 12 and on the way to Portugal now. Before it arrives your country, there will be no further update. It usually takes a months to reach. Wait patienly.

Are you kidding me? The order takes a month to arrive in Lisbon ??? see how long this order took RG862647162CN

Although they are both sent by China Post, they were sent from different cities in China. So, they may take different routes to deliver. The estimated delivery time for a China Post small packet to Portugal is 10-30 days. If there is any delay, it may need more times. No one could guarantee it could deliver within 10 days like RG862647162CN.

Good evening. I would like to know where is the order RO261752070CN .
