Could you tell me about some activities you have that day?  I really want to know. 

Sorry I don't have neither... People in Beijing also overlook it...

回復 @啊啊是誰都對：That's a pity

"Happy Valley" of our city will hold many Halloween activities

回復 @圓環之理：Which city do you live in? 

回復 @lizhenxuan：Shanghai
