My house faces south, and I want to open a west gate! I don't know if it's ok.

Geomantic speaking, the west is a white tiger, and opening the door in the west is the opening of the white tiger, which will eat people, so it is generally not opened. If you want to open it, you should set up a shadow wall (or shadow wall) in front of or behind the gate. Of course, you can open the door without being superstitious. In reality, there are several disadvantages in opening the door to the west. First, the sun shines directly into the house at night, and it may feel just right in winter and hot in summer; And the northwest wind is too strong in winter, which is too cold for the room.
