chin chang » china chang, chain change, china zhang
wang yang » wang liang, wang yanling
yang jie » yang jin, yang jui, yang xi
fong yin » fong ben, song yun, wong yi

• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang yang) OR (wang yan)) ((((yang jie) OR (yang yi))) OR (yang di)) chin chang fong yin lei ;~.
• Adding a wildcard symbol may retrieve word variants: ((wang yang) or (wang yan)) ((((yang jie) or (yang yi))) or (yang di)) chin chang fong yin lei ;*.
