Yes it is.
It is recommended not to sit at the office door, because the door is the passage for people to enter, the mouth of the office, and where energy enters, including both positive and negative energies. If you sit at the office door, your back has no support, and you are exposed to the chaotic energy from people coming and going. Over time, the person sitting in this position will often feel a subconscious sense of tension, sometimes feeling as if someone is watching them, leading to scattered thoughts, poor decisions, and an inability to focus on tasks. They may always feel restless, and even experience kidney problems, lower back pain, encountering troublemakers or unnecessary troubles at work.
So, the feng shui of sitting at the office door is very bad.
If your seat is at the office door, it is recommended that you change your seat.

1. The office door directly faces the internal office door, which is considered a "clash" in feng shui. The flow of energy tends to rush straight in, easily causing verbal disputes and personnel issues. When designing internal partitions, this should be taken into consideration.

3. The ideal position for the office door is on the left side, known as the "Green Dragon." If the door of a shop is on the left, business will be prosperous and bring good luck. For shops where the entire front is the door, the entrance and exit should be on the left side to bring good luck, which has the same effect as having the door on the left side.
