Trying to identify artists

I’ve recently received paintings from my late father and I’ve been trying to find information regarding the artists.

Any help would be much appreciated!

 

I tried adding the paintings but I guess the file is too large. I’ve put them all in an album on this site though.

 

Just in case someone else wrote the artist name without the "h" in it
Ku Fu-Sheng ...

From the same link, the chop looks correct ...



Same link, under "Works", a 1970 work has a similar feel. No examples from 1971, if he continued in that style.

See if the above gallery can provide any information.

 

Thanks, I wasn’t sure if it was the same person because of the missing h.
