Input:  Person1:     Could you tell me something about the Mid-Autumn Festival ? I find it also very interesting .  
 Person2:  OK . It falls on the 15th day of the eighth lunar month . It is said that there is a beautiful goddess Chang'E on the moon who had eaten some sort of elixir and had to depart her husband . She is always expecting to see her husband again . So , later we have the traditional idea that when there is the full moon , it is time for the family members to come together .  
 Person1:      So , I understand why people eat moon cakes on that day .  
 Person2:  You are right . In China , ' round ' is an auspicious word . The moon cakes are in round shape .  
 Person1:      Is it official ?  
 Person2:  It was not in the past . But from 2008 , we can enjoy a three-day holiday for this festival .
