Perhaps you should try some spelling variations:
thanh vi » hanh vi, thanh va, thanh ve
cua tre » cua te, cuu tre, cua triet
xuc gia » duc gia, luc gia, tuc gia
lam xuc » cam xuc, lam duoc
hieu va » hieu qua
lang xa » dang xay, lang van
lang ha » long ha
can ky » van ky, dan ky, ban ky
vi cua » vai cua, di cua
tu can » tu ban, tu cac, thu canh

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 can ky ((lang xa) OR (lang ha)) hoi. ((hieu va) OR (lieu va)) lam xuc gia thanh vi cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu can ky ((lang xa) or (lang ha)) hoi. ((hieu va) OR (lieu va)) lam xuc gia thanh vi cua tre~".
• Adding a wildcard symbol may retrieve word variants: tu can ky ((lang xa) or (lang ha)) hoi. ((hieu va) OR (lieu va)) lam xuc gia thanh vi cua tre*.
