Perhaps you should try some spelling variations:
yang guang » yan guan, yang liang
yang yang » wang yang, wang yan
tuan hua » tan hua, tuan vu, yuan hui
mei yung » pei yun, wei yang
pei yang » wei yang, hui yang, pei yun
i losung » die losung, iii losung, i long
losung 2 » losung 1, losung 5, losung b

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((((yang yang) or (qian rong))) or (yang guang)) tuan hua ((mei yung) OR (pei yang)) i losung 2 ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((((yang yang) OR (qian rong))) OR (yang guang)) tuan hua ((mei yung) OR (pei yang)) i losung 2 ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((yang yang) or (qian rong))) or (yang guang)) tuan hua ((mei yung) OR (pei yang)) i losung 2 ;".
• Adding a wildcard symbol may retrieve word variants: ((((yang yang) or (qian rong))) or (yang guang)) tuan hua ((mei yung) OR (pei yang)) i losung 2 ;*.
