What floor is 5- 1- 1504?

The naming method of users in the building depends on how the property in the current community is named, and the user's house number in each community is named differently.

For example, my home is the first household on the fifth floor of Building 5 1 Unit, 50 1.

My dormitory life is 5-624, which is 624 in Building 5.

There are also some naming methods based on the literal translation of Chinese equivalent to 1, floor 2, etc. In the past, floors were often named 1F, 2F and 3F, that is, 1st floor. With the increase of basement buildings, it is difficult to translate the negative 1 floor in spoken English. After the introduction of the translation of B 1, the underground part followed.
