HOW TO GO TO LOUHU AIGUOLU TRAIN STATION,,,

Do you mean you are staying at Aiguo Road, Luohu District?
If so, I do not think there is a train station on that road.
The nearest railway station is the SZ Railway Station.
From that road, you can walk to reach Cuizhu Station of Longgang Line, so you can walk to that station to take Longgang Line to reach Laojie Station. There you can change to Luobao Line to reach Luohu directly. Get out of the station, you can easily find the railway station.
