Perhaps you should try some spelling variations:
ban thanh » ban hanh, ban hang
qua cham » qua hai, qua cac, va cham
cham xuc » cam xuc, chat xuc, cham soc
nang xa » nang x, nang ma, mang xa
lang xa » lang ha, dang xay, lang van
va hanh » van hanh, va thanh, va danh
cua tre » cua te, cuu tre, cua triet
tu can » tu ban, tu cac, thu canh
can ky » van ky, dan ky, ban ky
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 can ky ((nang xa) OR (lang xa)) hoi. hieu qua cham xuc ((va hanh) OR (ban thanh)) vi cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu can ky ((nang xa) OR (lang xa)) hoi. hieu qua cham xuc ((va hanh) or (ban thanh)) vi cua tre~".
• Adding a wildcard symbol may retrieve word variants: tu can ky ((nang xa) OR (lang xa)) hoi. hieu qua cham xuc ((va hanh) or (ban thanh)) vi cua tre*.
