What bus should I take from Chang 'an to Humen South Gate Fifth Industrial Zone?

It's really hard to tell which industrial zone it is, but there is a cross-town bus from Songshan Lake to Humen Weiyuanbao passing through the South Gate. I saw many big factories when I passed by by car, such as Henkel (National Starch) Factory. I wonder if it is the fifth industrial zone. After Chang 'an Station (it seems that it doesn't enter the station), this train goes to Zhen 'an Road-Humen in the evening, instead of taking the old national road 107, with a blue body. You can ask.
