Hefeinan Railway Station - hotels & luggage storage

Yes, near the railway station, there are a lot of hotels in different standards within walking distance.
Green Tree Inn, located at No. 30 Dongliu Road.
Yaqi Business Hotel, located at No. 118 of Luzhou Avenue.
Hanting Hotel, located at the intersection of Middle Wanghu Road and East Wanghu Road.
In the railway station, there is left luggage service, you can deposit your luggage there.

Any idea how much they charge to store luggage at the Hefeinan Railway station? Is it open 24 hours a day?

The hotels listed above actually are around 3km away from the rail station. As it is a new station, it is hard to find a good hotel within walking distance.

The official left-luggage counter does exist, but I am not clear about the charge. And as I know, it is not open for 24h.
