Perhaps you should try some spelling variations:
thanh vi » hanh vi, thanh va, thanh ve
va thanh » gia thanh, ban thanh, va tinh
dang xay » dang van, van xay
cua tre » cua te, cuu tre, cua triet
cam tuc » cam xuc, cam tu, nam thuc
hieu va » lieu va
dang xa » lang xa, dang ha, dang va
sac ky » cac ky, sai ky
tuc va » thuc va, truc va, tuc xa
vi cua » vai cua, di cua
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) OR (dang xay)) hoi. ((hieu va) OR (hieu qua)) cam tuc va thanh vi cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sac ky ((dang xa) OR (dang xay)) hoi. ((hieu va) or (hieu qua)) cam tuc va thanh vi cua tre~".
• Adding a wildcard symbol may retrieve word variants: te sac ky ((dang xa) OR (dang xay)) hoi. ((hieu va) or (hieu qua)) cam tuc va thanh vi cua tre*.
