How to read the number of exhibition hall?
The English letter (A, B, or C) denotes one of the three major exhibition areas, and the Arabic number (1~16) after the letter but before the decimal point indicates one of the 16 exhibition halls in the three areas. Halls 1-8 are in Area A, Halls 9-13 in Area B, and Halls 14-16 in Area C. The numeral after the decimal point means the level of floor. So, A2.2 refers to the exhibition area on floor 2 of Hall 2 in Area A.
