Which floor of "The Fire of Life" in 1979 is not suitable for sharing?

In 79, the fire of life failed to live in 1 building.

The first floor and the sixth floor are the most taboo floors for people with the fire of life, because these two floors are not only relatively low, but also belong to water. Water can put out the fire, so it will inhibit the fortune of people in the fire of life. People who belong to the five elements of life should not move to floors like the first floor and the sixth floor in order not to affect their good luck. If they live in it for a long time, they will find that their wealth is declining. The fire is rising, so people with the fire of life are suitable to live on middle or high floors. Compared with existing buildings, the first and sixth floors are relatively low, which is not suitable for people in the fire of life.
