What are the Feng Shui requirements for the door design of an office building?

The door is not only the facade and external image of a company, but also the passage through which people and goods flow, and is the entrance to receive Qi. Therefore, the Feng Shui layout of the door is very important to a company. The gate is the opening of a company, and the opening should not be too narrow. The wider the gate, the more auspicious it is; the position of the gate must be on the left side of the company, because the left side means "a dragon's mouth opens, and gold and silver are poured out."
