The best way to solve the suffocation from the gate is to put the five emperors' ancient money in order under the threshold of the gate. From the left are Jiaqing, Qianlong, Yongzheng, Shunzhi, Kangxi and Daoguang. This will help to relieve the suffocation of outdoor flushing and prevent the air from leaking out of the house. Note that the threshold should be four points higher, and the ancient coins should be placed neatly (indoors facing the gate, the order is Shunzhi/Kangxi/Yongzheng/Qianlong/Jiaqing). At the same time, put the feet of ancient money inward and the face of money upward. Some emperors' names are literal. If we put the feet of ancient money outward, it will lead to discouragement in the house. If the gate cannot be used as a threshold, you can string the money of the five emperors and hang it on the threshold. The effect is definitely not as good as that under the threshold. There are more Sha Qi outside the window than at the gate, but because the window is not a place for people to go in and out, the flow of gas is not as big as that of the gate. Common Sha Qi include the bow-bending, rushing, stabbing, reflecting, cutting Dreadwind, white tiger, and Sha Qi caused by seeing chimneys or flagpoles. If you see these Sha Qi outside the window, you'd better add them to the Feng Shui items besides putting related Feng Shui items (such as gossip).
The second method is to put five sets of five emperors' money in the four corners and the center of the house in turn. Because the room is relatively large, a set of five emperors' money can't be used because the strength is not enough. Five sets of five emperors' coins are placed facing the gate, with five Kangxi in the left corner, five Yongzheng in the right corner, five Qianlong in the left back corner and five Jiaqing in the right back corner. This practice requires five sets of five emperors' money to be buried underground, so it is best to do it before joining the job.
