lang yang » wang yang, yang yang, lang lang
yang xing » yang jing, yang liang, yang using
xing gao » qing gan, ring gai, xin guo
wu zhong » yu zhong, hua zhong, hu hong
gao xin » guo xin, gao ying

• Adding a wildcard symbol may retrieve word variants: ((lang yang) or (ylang ylang)) yang xing gao xin ((wu zhong) or (2 zhong)) sau ;*.
