chng about » thing about, teng about, caring about
dong yang » dong hoang, wang yang, yang yang
tin hong » tan hong, kia hong, thi hong
hong yu » wong yue
test a » test _, test 4, test 5
a tin » a tiny, _ tin, a ten

• Adding a wildcard symbol may retrieve word variants: dong yang ((wang about) OR (chng about)) test a tin hong yu ;*.
