Perhaps you should try some spelling variations:
khoi tang » kho tang, khoi nang, thoi trang
cac khoi » cac thoi, cac khoan, cach thoi
tang mai » tang ma, tang tai, lang mai
ban hanh » ban hang
cham xuc » chat xuc, cham soc, pham duc
hieu va » lieu va, hieu qua
hieu ve » hieu van
mai hoi » mai khoi, dai hoi, lai hoi
cua tre » cua te, cuu tre, cua triet
vi cua » vai cua, di cua

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: tu cac khoi tang mai hoi. ((hieu ve) OR (hieu va)) ((cham xuc) OR (cam xuc)) ban hanh vi cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu cac khoi tang mai hoi. ((hieu ve) OR (hieu va)) ((cham xuc) or (cam xuc)) ban hanh vi cua tre~".
• Adding a wildcard symbol may retrieve word variants: tu cac khoi tang mai hoi. ((hieu ve) OR (hieu va)) ((cham xuc) or (cam xuc)) ban hanh vi cua tre*.
