1. The natural performance of commercial office buildings, institutions and villas is also excellent, and the size of the gate is moderate. It is the facade of a house. It should be smooth and bright. From ancient times to today, emperors and ancient buildings have left bright, wide and flat copper products, which should not be dim and complex. The size of the door is the same as that of the house, and the copper door combines anti-theft and entry into the house, which should not only match the size of the pattern. The door of the house is small, or the door of the house is large. The style is advanced, and it should be moderate in sterilization, fire prevention, anti-corrosion, anti prying and bad luck. The door of the house is large, and the air comes out immediately. It has excellent performance in dust prevention. Come on, it's easy to lose money if you can't keep it. If it is too small, although money will not leak, people will become narrow-minded, stingy and unlucky, so the size of the door should be moderate.

2、门的正向不要有他人的屋脊、飞檐、兽头、道路等之不吉物冲射。如果是道路的冲射，若合于元运则吉，则有“冲起乐宫无价宝”之誉。道路的冲射，不合于元运则凶，可以用树木遮挡或大门移位。所遮挡的树木要注意不能过高，否则气口遮住，阴气则太盛，又主多病。

2. Don't have other people's roofs, cornices, animal heads, roads and other unlucky things shooting at the front of the door. If it is a shot from the road, if it is in line with Yuan Yun's Qi, it will be auspicious, and it is known as "a priceless treasure in the music palace". The impact of the road is not consistent with the yuan Yun, so it can be blocked by trees or the gate can be shifted. The sheltered trees should not be too high, otherwise the breath mouth is covered, the Yin Qi is too abundant, and the main disease.

3、房子的正面不要对祠堂，神庙，一般的说法祠堂神庙是神鬼的居处，阴气十分重，阴气重也就是煞气重，大门是需要开在生气之方，也就是阳气重的地方，因此大门对着祠堂是千万要避免;祠堂神庙若在房子的后面亦不宜。容易出通灵者、酒鬼、神志不清，无所事事的人。

3. The front of the house should not face the ancestral temple or temple. Generally speaking, the ancestral temple is the residence of gods and ghosts. Yin Qi is very heavy. Yin Qi is heavy, that is, evil Qi is heavy. The door needs to be opened in the angry side, that is, where Yang Qi is heavy. Therefore, the door facing the ancestral temple should be avoided; If the ancestral temple is behind the house, it is not suitable. People who are prone to psychics, alcoholics, delirious and idle.

4、门正向有对面房子的屋脊尖角，宛加对着一把利刃，不但对住宅中人的健康极为不利，也会影响到人与人相处之间的友好，对家中财运也是极大的损伤。

4. The door is facing the sharp corner of the ridge of the opposite house. It looks like a sharp blade. It is not only extremely harmful to the health of people in the house, but also affects the friendship between people and the wealth of the family.

5、门口不宜有大树遮挡。门口为整个住宅的气口，通过这个囗，才能把好的气引进，如果被大树一挡，通风不良，阳气进不去，阴气又出不来，阳光被遮住，使住宅产生阴湿，故为凶。树木不可枝干太盛而盖到屋顶，将影响通风和日照，令住宅阴湿不堪。

5. The door should not be sheltered by big trees. The doorway is the air outlet of the whole house, through which good air can be introduced. If it is blocked by a big tree, the ventilation is poor, the Yang air cannot enter and the Yin air cannot come out, and the sun is covered, which makes the house cloudy and wet, so it is fierce. Trees should not be covered to the roof with too many branches, which will affect ventilation and sunshine and make the house damp.
