When you say the door faces the kitchen diagonally, do you mean the kitchen door? If so, it violates Feng Shui. Make a porch at the entrance or place a pot of green plants between the two.
Remember another point, if there are floors in the house, try to set the dining room in a raised position, and the dining table is best set in a location with strong air flow, which is good for family members
1. The stove in the kitchen should not face the door - it means that a woman will suffer from poor health, gastrointestinal problems, lack of wealth, and headaches.
2. The kitchen stove should not be facing the refrigerator - the host family is not in good health and relatives often take medicine.
3. The kitchen stove should not face the bedroom door - the housekeeper will be quarrelsome, grumpy and neurotic.
4. Do not place large amounts of kitchen appliances - the main residents may suffer from backache, headache, and stomachache.
5. The balcony walkway should not face the stove - it will not attract wealth, back pain, and high blood pressure.
I hope my answer can help you,
