Perhaps you should try some spelling variations:
thanh va » thanh van, hanh va, thanh ha
thanh vi » hanh vi, thanh ve, nhanh vi
cua tre » cua te, cuu tre, cua triet
cam tuc » cam xuc, cam tu, nam thuc
dang xa » dang xay, lang xa, dang ha
hieu va » lieu va
ky dang » ky nang, ky danh
sac ky » cac ky, sai ky
tuc va » thuc va, truc va, tuc xa
te sac » te sach, te cac, te san

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 sac ky dang xa hoi. ((hieu va) OR (hieu qua)) cam tuc va ((thanh vi) OR (thanh va)) cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sac ky dang xa hoi. ((hieu va) or (hieu qua)) cam tuc va ((thanh vi) OR (thanh va)) cua tre~".
• Adding a wildcard symbol may retrieve word variants: te sac ky dang xa hoi. ((hieu va) or (hieu qua)) cam tuc va ((thanh vi) OR (thanh va)) cua tre*.
