You are required to show your attempt at working this problem before we can offer tutorial help. How should you approach this problem?

It is difficult to read and understand what you are trying to do. Can you say in words what your approach is? Also, it's better if you learn to post in LaTeX for math equations. See the LaTeX Guide link in the lower left of the Edit window.

Finally, the circuit diagram is confusing. Is there a short circuit wire across the $4\Omega$ resistor at the left of the schematic?

In this example,mn is short circuit,and we have a simple circuit,where I can easily count the numbe of mesh (or loop?) by randoml way and its 2 in this pariticular case, p----g、a-g-p-o-b.What if I encounter a more complicated one such as the one shown below,how should I count it ,are there and standralized procedures for doing it ?
