Reject task to any node

I'm a freshman. I'm learning Activiti, the version is 5.18.

This is xml code:

My question is : when i approval task3,  this task don't pass. Then, turn to task1 from task3. How can i implement this?

[ctsarsonas]

Have you ever use the Exclusive gateway symbol?

Add this to your diagram then set the sequence flow's flow condition section applying the output result from the previous task.

[yangfan]

Yeah, that's really a good idea! Thanks!

If there are so many nodes, such as seven nodes, I want to turn to any node from one node, for example, sixth to first、sixth to second... sixth to fifth.

In this case, maybe Exclusive Gateway is not a good way. Because, painting so many lines from sixth to others is necessary. 

I want to simplify the diagram and control by code.

Any other good ideas?
