chang min » zhang ming, chang mae, chan ming
chang ann » chang won, chang yun, change annex
chan kang » chung kang, chan eng, chan fong
zhong zhi » zhang zhi, hong ghi, zhong tai

• Adding a wildcard symbol may retrieve word variants: wang yang yan han shen ((((chang min) or (chang ann))) or (chan kang)) zhong zhi ;*.
