Where is Shenyang adult products wholesale market?

There is an adult street near Shenyang Railway Station. You start from the junction of Shenyang Railway Station and Zhonghua Road and walk more than 30 meters. There is a small alley on your left. There seems to be a Japanese fast food restaurant next to the alley, that's all. Basically, they are in the form of small shops, and some are wholesale, which is quite big. Might as well go and have a look.
