Perhaps you should try some spelling variations:
yang guang » yan guan, yang liang
yang yang » wang yang, wang yan
ii losung » iii losung, i losung, 3 losung
yuan hui » yuan fei, jaan hui, tuan hua
hui yang » hui ying, du yang, h yang
hui hui » huo hui, chun hui
ii long » i long

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((yang guang) or (yang yang)) yuan hui hui yang ((((ii long) OR (ii losung))) or (die losung)) du ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((yang guang) OR (yang yang)) yuan hui hui yang ((((ii long) OR (ii losung))) OR (die losung)) du ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((yang guang) or (yang yang)) yuan hui hui yang ((((ii long) OR (ii losung))) or (die losung)) du ;".
• Adding a wildcard symbol may retrieve word variants: ((yang guang) or (yang yang)) yuan hui hui yang ((((ii long) OR (ii losung))) or (die losung)) du ;*.
