Is it cold to go to Heze by train from Qingdao at night?

Departing at 8: 22 p.m. and arriving at the station at 5: 48 a.m., I almost drive at night, especially in the middle of the night, and the temperature is very low in the last two days, so the bus is often late, so I need to bring more warm clothes, whether it is a hard seat or a sleeper, which will not be very comfortable. If only Heze had an airport, O(∩_∩)O haha ~
