Help with identification: chinese bowl with blue mark

[Misslautrec]

Hi everyone! Hope you are all having a great day.

I write here to seek some help to identify a chinese bowl that I have. I do not know if it is fake, o a replica, or authentic. I have been investigating on my own but my knowledge is not enough for this. In this case this bowl has only 2 symbols in its bottom, not 4, just 2, handpainted. 

Could someone please give me some information, ideas, advice..? I have seem some bowls with this same design but with different signatures. In the picture i put the signature in two different perspective as I dont know the right way to read it.

Thank you!

The question about authenticity does not arise with such items as they are still being made/used. This one appears to be from the 20th century (mark is stamped), probably second half, but could also be a bit earlier or later. Not antique but perhaps vintage.
