Excuse me, which direction should the chandelier in my restaurant be installed?

According to the long dining lamps on the dining table, we can see that there are three lamp holders on the balcony and living room, the lowest lamp holder leans against the wall, and the height difference of each lamp is about 10 cm, so that the wall can be installed in a straight line between the installation direction and the balcony living room.

The round dining lamp is installed directly above the dining table, and three lamp holders can be directly seen in the balcony and living room. The height of the lamp holder refers to the height of the room.
