Perhaps you should try some spelling variations:
thien van » thi van
hieu van » hieu va, lieu va, hieu ve
cam tuc » cam xuc, cam tu, nam thuc
va hanh » van hanh, va thanh, va danh
hai cua » thai cua, dai cua, hoi cua
te cac » tu cac, ve cac, te cao
tuc va » thuc va, truc va, tuc xa
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: te cac ky nang x ho. ((hieu van) OR (thien van)) cam tuc va hanh ((vi cua) OR (hai cua)) tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te cac ky nang x ho. ((hieu van) OR (thien van)) cam tuc va hanh ((vi cua) or (hai cua)) tre~".
• Adding a wildcard symbol may retrieve word variants: te cac ky nang x ho. ((hieu van) OR (thien van)) cam tuc va hanh ((vi cua) or (hai cua)) tre*.
