What does the No.2 bus stop at the eighth floor mean?

This is the lyrics of the first snow in Dao Lang in 2002, in which:

1, the eighth floor is the Kunlun Hotel in Xinjiang, which was built in 1959 and was the tallest building in northwest China at that time. A * * * has eight floors, so citizens used to call it the "eighth floor", which belonged to the name of a bus stop such as Urumqi No.2 Road and No.52 Road at that time. Because most citizens are more familiar with the eighth floor than Kunlun Hotel, on 2011year1October 23rd, Kunlun Hotel hung these two red lettering with a width of 2.2 meters on the front of the middle building.

Bus No.2 and Bus No.2 of Urumqi Bus Company starts at the South Railway Station and ends at the machinery factory. 2011September, with the operation of Urumqi urban rapid transit (BRT 1 line), Bus No.2 was gradually cancelled.

Now there is the site name "Eighth Floor", mainly the BRT 1 and Line 2 sites, and the building "Eighth Floor" also exists.
