I will arrive at Changchun airport at 6 pm and then go to Songyuan? How can I walk fast? And convenient? For the first time, I went to ask the great god for advice

First of all, there must be no bus to Songyuan at the airport at 6 o'clock. You have two choices:

Stay near the North Station and leave the next morning. Take a bus at Kaixuan Road Passenger Station in the north exit of Changchun Station. The earliest bus leaves at 6.30, 10 minutes.

You can choose these evening trains.

It's not cheap to take a taxi from the airport to the station. It is best to take the bullet train from Jilin to Changchun. It's fast and cheap, so it's convenient to transfer if you buy one from North Station.

Take it with your hands!
