The first line contains an integer T ( T < 20) indicating the number of test cases.
Each test case begins with a line containing four integer: fx fy tx ty(-5000<=fx,fy,tx,ty<=5000). The knight is originally placed at (fx, fy) and (tx, ty) is its destination.
The following line contains an integer m(0 < m <= 10), indicating how many kinds of moves the knight can make.
Each of the following m lines contains two integer mx my(-10<=mx,my<=10; |mx|+|my|>0), which means that if a knight stands at (x,y), it can move to (x+mx,y+my).
