How can i make arrows like this?

arrow diagram

This is what I've done so far.

\documentclass[10pt,a4paper]{article}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage[left=22mm,bottom=22mm,right=28mm,top=30mm]{geometry}
\usepackage{tikz}
\usetikzlibrary{shapes,arrows}
\begin{document}
\pagestyle{empty}

% Define block styles
\tikzstyle{decision} = [diamond, draw, fill=blue!20, 
    text width=4.5em, text badly centered, node distance=3cm, inner sep=0pt]
\tikzstyle{block} = [rectangle, draw, fill=blue!20, 
    text width=2cm, text centered, rounded corners, minimum height=10mm]
\tikzstyle{line} = [draw, -latex']
\tikzstyle{cloud} = [draw, ellipse,fill=red!20, node distance=3cm,
    minimum height=2em]
\begin{center}
\begin{tikzpicture}[node distance = 3.4cm, auto]

 \node  [block,yshift=30mm] (1) {1};
      \node [block, xshift=-30mm] (2) {2};
      \node[block, xshift=-60mm] (3) {3};
\node [block, xshift=-90mm] (4) {4};
        \node [block, xshift=-120mm] (5) {5};

       \node [block,yshift=30mm, xshift=-45mm] (6) {6};
         \node [block,yshift=-40mm, xshift=-105mm] (7) {7};
     \node [block,yshift=-60mm, xshift=-105mm] (8) {8};
             \node [block,yshift=-25mm, xshift=-75mm] (9) {9};
\node[block, xshift=-60mm,yshift=-60mm] (10) {10};
\node [block, xshift=-30mm,yshift=-60mm] (11) {11};
\node[block, xshift=0mm,yshift=-60mm] (12) {12};

\draw[->,>=latex'] (4) -- (3);
\draw[->,>=latex'] (3) -- (2);

\end{tikzpicture}
\end{center}
\end{document}

    One trick is to use \draw (9) -| (7); Another is to locate a corner using \coordinate (97) at (9 -| 7); Commented May 17, 2017 at 23:51

    Why did you delete everything in both your question and my answer?

    That's ridiculous. Why ever not? You may be able to delete it. I'm not sure. But it will still be there. Deleted posts are still on the site. Why did you post on a public website if you didn't want it here? This is how the site works: your question stays for other users.

    I've flagged this for the mods to rollback.

    What do you mean? I said it is public - nothing about its being popular. What difference does that make?

A bit of a miscellany ...
