Power bank left at CAN

Hello!
My name is Corina Topor and I'm from Romania. Last year when I was going back to my country from Guangzhou, I had in my luggage 2 power banks and the airport stuff take it out of my baggage because it wasn't allowed to keep it inside. Now I'm in the city again and I want to know if I can have back my power banks. This is my flight ticket from last year.
Thank you!
