The two maps demonstrate the arrangements of a trade show floor in 2009 and 2010.
Generally, there is not a huge difference between these years except the exchanged location of Conference Hall and Exhibition areas. Meanwhile,the exhibition areas tripled and had more seats in 2010 than in 2009.
The main entrance, refreshment and side entrance lied on the east of the floor correspondingly, which remained at the exactly same place in 2010. Besides，the conference hall was constructed where the exhibition once located, from west to North-East, with decreasing in size. Concurrently, an obvious expansion of display stands can could be seen in 2010 in exhibition area.
There was another striking change can be observed is the meetings room, which was next to the conference room in 2009, and was eliminated in 2010, that gave enough space for the expansion of Exhibition area.
