What you have is not $A\cap C\ne \emptyset$

You don't have to use perfect circles in Venn diagrams. Try more complex figures!
Also you don't have to show the intersections with shadows only! You can try figures containing objects.

Hello, paulmdrdo!

Find a Venn diagram containing three sets $$A, B, C$$ such that:
$$A\cap B\,\neq\,\emptyset,\;B\cap C\,\neq\, \emptyset,\,\text{and }C\cap A\,\neq\,\emptyset$$
but $$A\cap B\cap C\,=\,\emptyset$$

Here's my answer; please check if it is right.

No.

You have: $$C \cap A \,=\,\emptyset$$The diagram might look like this:

              *               *
            *   *           *   *

      *       A       *       B       *
    *               *:::*               *

              |       C       |
              |               |
