Feng Shui, what does it mean to string tang style?

The so-called hall is that the door is facing the back door or the front window is facing the back window, and the entrance door is facing the back window. As long as the vents on the outermost periphery of the house are opposite and there is no light-transmitting object in the middle, this is the hall. The function of the hall is to come out as soon as the gas enters the room, and not to gather gas or wealth. Passing through the hall will also cause the rapid flow of gas field in the house to be extremely unstable, which is prone to the effect of lotus accident. Because it is extremely serious, it is commonly known as the first suffocation of Yangzhai.
