1, change the window to feng shui: in feng shui, it is good to have a famous hall in front of the door. If there is greening, flat land, pool, parking lot, etc. In front, opening the middle door is the first choice. If there is no famous hall in front, it is better to open the door on the left, because on the left is Qinglong, which is auspicious. The white tiger on the right is generally considered inferior, so it is not good to open the door on the right. It is a worse choice to open the North Gate as Xuanwu Gate, which means "losing". Therefore, the house should carefully open the north gate.
2. The traditional four directions of China are symbolized by Suzaku, Xuanwu, Qinglong and Baihu. The corresponding azimuth formula is: "Former Suzaku, Back Xuanwu, Left Qinglong, Right White Tiger." Therefore, there are four main options for setting the door opening direction of a general house, namely, opening the south gate (Zhuquemen), opening the left gate (Qinglong Gate), opening the right gate (Baihumen) and opening the north gate (Xuanwu Gate).
