chinese porclain ??

Hi
I have some teacups/saucers in a removal box at home and was wondering if these markings are known ? I have no clues at all and assume they're the usual stuff people send in!
I hope you can see/read them. The dish with the picture shows basically whats on all pieces. Pretty thin pieces of (bone) china?

Worth anything do you think ? Or can I just throw/give them away?
Thanks for your time and any responses !
