Perhaps you should try some spelling variations:
thanh vi » hanh vi, thanh va, thanh ve
cua tre » cua te, cuu tre, cua triet
tuc gia » tac gia, duc gia, toc gia
xuc gia » duc gia, luc gia, quoc gia
hieu va » lieu va, hieu qua
lang xa » dang xay, lang van
lang ha » long ha
can ky » van ky, dan ky, ban ky
va lam » van lam, va lap
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 lam ((xuc gia) OR (tuc 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 lam ((xuc gia) OR (tuc gia)) thanh vi cua tre~".
• Adding a wildcard symbol may retrieve word variants: tu can ky ((lang xa) or (lang ha)) hoi. hieu va lam ((xuc gia) OR (tuc gia)) thanh vi cua tre*.
