The second TV CF of the Incheon World City Festival which features SNSD as its sponsor [I think the girls are its host or ambassador, not 'sponsor' sponsor -Soofany] will be aired on August 7th, along with its opening performances.

On the 22nd, the festival organization committee said that SNSD has been filming from 5 in the morning until midnight on August 21st, at the World City Festival’s main performance centers such as the Teddy Bear Hall, World Culture street, a themed movie theater, a music fountain, etc.

The festival organization committee revealed that “the production of the second CF was filmed at the festival’s main performance center locations, which was different from the first TV CF” and “because of SNSD’s lively image, you think that you’ll have lots of fun if you go to the World City Festival.”
