yang guang » yang yang, yan guan, yang liang
tan hua » tuan hua, wang hua, tan chia
hua pei » hua wei
yang de » yang di, yang d, yang du
long du » long d, long run, long did
long do » long d, longer do, long ago

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

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