All those parcels are fine and on their way. What kind of delivery times are u expecting?? 1 week? 2 weeks?? The answer is probably up to 12 weeks! Not to mention that the mess which is happening in Greece wont be helping cos lack of funds will mean understaffed post office and the general social unrest will cause even more delays.

Postal times depend on many factors. Nobody can say what is the specific reason for any experienced delays. U should look up the delivery times for Greece:

After that, u also need to account for the social unrest/understaff in greece. For your case, the most probable delivery times is somewhere around the 8 weeks period. U have reported 56 days waiting for previous item so u already know how long u need to wait.

Maybe your items were shipped during a busy mail period in China or in the transiting countries. Its very unlikely your items will travel to greece via direct flight. It will transit several countries along the way and any mail delays in those countries will also affect your parcels. Like i said, there are many factors contributing, impossible to pinpoint any one cause. The most likely result is that the new waiting time is now almost 2 months; this will be the new norm so u should keep this in mind if u decide to use chinapost to ship items from china.
Ebay waiting times is outdated becos it was based on data from long time ago. Usually, the period u are told to wait is just the max delivery time for an item to arrive any country using a specific carrier, ie, chinapost. It has not accounted for the gradual increase in mail volume or any specific conditions that have arisen since then, eg greece economic problem etc.

shipping time from china to greece is not stable. Fastest arrival takes only 2 weeks, however slowest arrival time can take 2 months.
Your parcel is still in normal time frame, please be patient.
