Hiii.. what attraction can we see if we go to Harbin on October?

As I know, there are many popular scenic area in this area.
Sun Island Scenic Area, Siberian Tiger Park, St. Sophia Church and Central Street are must sees. In addition, you can easily find some nice restaurants and taste distinctive local foods.
However, the best time o visit it is February and March, when the Ice and Snow Festival is held. But it will be extremely cold then.
