huang ying » huang jing, huang ting, huang yang
rein gang » ein gang, ein ganz, den gang
deng gang » den gang, der gang, gong gang
hong shu » cong shu, tong shui, wong shiu

• Adding a wildcard symbol may retrieve word variants: wang huang ying i ((rein gang) or (deng gang)) li ((hong shu) or (wong yue)) ;*.
