Changchun snow and ice festival

My research indicates that the city also has an Ice and snow festival similar to Harbin. We are already going to the Harbin festival but looking at stopping in the city for two nights on our return south and would like to see the festival there also. Any information would be appreciated EG where is the festival located, how to get there from the city, how much is entry fee.
Additionally we are travelling from Harbin to CC by High speed train which stops at the CC west station. How far is it back into the city and are Taxis readily available. As we only have a short amount of time what other things are worth seeing there. Any information would be greatly appreciated.

Regards
