Everything tagged: Chelang Point

I am trying to identify and locate two geographical references referred to in U.S. Army Air Forces after-action reports written in 1945.

The first is Chelang Point, which is apparently on the south China coast.  Does anyone know where this is, and what the contemporary name might be?

The second is Tungku Island, said to be in the mouth of the Canton River.  Again, does anyone know where this particular island is, and what its contemporary name might be?

I'll be greatly appreciative of any help with this puzzle. 

Thanks!
