Phoenix building refers to the "second top floor", that is, the second highest floor of each building, which is both high and comfortable. Moreover, such a floor is not only very well ventilated, but also full of light. Compared with the top floor, users don't have to worry about water leakage, so Phoenix Building is the first choice for people to buy a house.
The reason why this "myth" is named is mainly because the top floor is high, just like a towering tree, which can let the phoenix live in, so it is called Phoenix Building. On the other hand, the second top floor is often loved by many experienced buyers, so it is called "Phoenix Building".
