Perhaps you should try some spelling variations:
gender working » gender hiring, gender work
working gang » working long, working man, working hand
wang yang » wang yan, wang liang, wang yanling
gang und » lang und, zugang und, zwang und
und ab » und abs
fan a » fang a, fan _, far a
can a » can _

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yang ((fan a) OR (can a)) gender working gang und ab ;~".
• Adding a wildcard symbol may retrieve word variants: wang yang ((fan a) OR (can a)) gender working gang und ab ;*.
