Hi! I need help with tracking these 3 packages that were sent by China Post (to Portugal)

RB540009001CN and RB773610885CN - Last status is NULL at Beijing Airport and NULL at Shanghai Airport, respectively. Does it mean in they are waiting for transport to Portugal?

RB711544183CN and RB800096734CN- Last status is "Opening", I have learned this means it is being inspected by customs. Does it take too long for them to inspect? It's been stuck like that since the 10th and 11th.

Also, I've seen that there has been a typhoon going past China lately, I don't know if it will affect these areas.
