Perhaps you should try some spelling variations:
gesetzen iii » gesetzes iii, gesetz iii, gesehen iii
der gesetzen » der gesetze, der gesellen, der gesetzlichen
yang guang » yang yang, yan guan, yang liang
yan gang » yan wang, yang yang, yan liang
ji zhong » wu zhong, yu zhong
2 zhong » 2 hong, wu zhong, yu zhong

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

• If you are trying to use Boolean operators, they must be ALL CAPS: wing ((yan gang) OR (yang guang)) der gesetzen iii ((ji zhong) OR (2 zhong)) di ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wing ((yan gang) OR (yang guang)) der gesetzen iii ((ji zhong) or (2 zhong)) di ;~".
• Adding a wildcard symbol may retrieve word variants: wing ((yan gang) OR (yang guang)) der gesetzen iii ((ji zhong) or (2 zhong)) di ;*.
