longer do » longer _, longer a
yang y.c » yang yi, yang yao, yang yue
yang 4.3 » lng 4.3, yang 47
tan hua » tuan hua, wang hua, tan chia
hua pei » hua wei
long do » long d, long du, long ago

• Performing a fuzzy search may retrieve terms with similar spellings: ((you liang) or (yang guang)) tan hua pei ((yang y.c) or (yang 4.3)) ((long do) OR (longer do)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((you liang) OR (yang guang)) tan hua pei ((yang y.c) OR (yang 4.3)) ((long do) OR (longer do)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((you liang) or (yang guang)) tan hua pei ((yang y.c) or (yang 4.3)) ((long do) OR (longer do)) ;*".
