I have heard that the main door should not face directly at the kitchen door due to the Flow of "Qi" will quickly flow out through the back door. To prevent this, there should be a wall in between to enhance circulation in the house. The question now is that, is it really need a wall or can it be replaced by other types, eg: screen or divider. If it is possible, is it enough just to block the view of the kitchen door once i entered from the main door? Also, will the "hu lu" play a part by hanging at the window in the back door to reduce the quick outflow of "Qi"? Furthermore, from your article, i read that the "Pa Kau" with the mirror in the middle can also used to cure the straight Flow of "Qi", but it did not indicate where should i hang the "Pa Kau".
