yang fan » zhang fan, yang dean, yang yang
yu zhong » wu zhong, yu zheng, hu hong
hai song » hai phong, hays song, a song
song seo » hong seo, song so, song seng
2 zhong » 2 hong, ji zhong, wu zhong

• If you are trying to use Boolean operators, they must be ALL CAPS: wang ((yang fan) OR (wang yan)) ((hua zhong) OR (((yu zhong) OR (2 zhong)))) shang hai song seo ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((yang fan) or (wang yan)) ((hua zhong) or (((yu zhong) OR (2 zhong)))) shang hai song seo ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((yang fan) or (wang yan)) ((hua zhong) or (((yu zhong) OR (2 zhong)))) shang hai song seo ;*.
