That's a real T-junction.
If you go from the railway station to the Martyrs Cemetery, you should take the bus 1 and get off at Zunyi Hotel Station instead of Honghuagang.
After getting off, take Shilong Road (Zunyi Hotel stands at the intersection of Shilong Road and Ziyin Road), go straight for 200 meters to Shilong Bridge and cross the river.
Turn left and go straight for 200 meters to the Martyrs Cemetery.
