zheng lei » zhang lei, zheng lili, zhen wei
kai wang » kai fang, kai hong, li wang
lei chen » li chen, frei chen, lei sheng
yang jui » yang judy, yang di, yang xi
chang ha » chang mae

• Adding a wildcard symbol may retrieve word variants: kai wang zheng lei chen ((yang jui) or (yang yi)) chang ha ;*.
