Thank phuong phuong for your precious advice . I will remember that . In life , anyone has  some trouble . Of course , they must rise after falling because "  your life wasn't belonged to you as soon as you was born , it is belonged to your family , your nation and your world "      I also have some advice for you :
  1. You can fail in this war , and next one... and also next one . BUT you must succeed in the last one
  2. Be patient and you will succeed!
