Will the shoppings malls be closed on Oct. 29 to Nov 2, 2012 because of the Expo ?

We will be travelling to Guangzhou on October 29, 2012 until Nov. 2, 2012. I heard that this coincides with the Expo or the trade fair and they told me that malls such as the bag city will be closed during these days. Will all the shopping centers be closed during these days. Thank you for your response
