Perhaps you should try some spelling variations:
te sach » toc sach
danh vi » hanh vi, dinh vi, danh di
hieu vu » hieu va, hieu ve, hieu su
vu cham » va cham, vu kham, tu cham
va lang » va nang, hoa lang
xa lang » ba lang, ha lang, xa bang
cua tre » cua te, cuu tre, cua triet
xuc va » duc va, tuc va, luc va
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 sach ((xa lang) OR (va lang)) xa hoi. hieu vu cham ((xuc va) OR (tuc xa)) danh vi cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((xa lang) OR (va lang)) xa hoi. hieu vu cham ((xuc va) or (tuc xa)) danh vi cua tre~".
• Adding a wildcard symbol may retrieve word variants: te sach ((xa lang) OR (va lang)) xa hoi. hieu vu cham ((xuc va) or (tuc xa)) danh vi cua tre*.
