Perhaps you should try some spelling variations:
sach ky » sac ky, sach ty, sach kem
nang xa » nang x, lang xa, nang ma
hieu ve » hieu va, hieu van
truc va » thuc va, thuc vat, trung va
cua tre » cua te, cuu tre, cua triet
ve cam » ve cham, ve cac, va cam
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: su ((sach ky) OR (sach y)) nang xa hoi. hieu ve cam ((xuc va) OR (truc va)) hanh vi cua tre~.
• Adding a wildcard symbol may retrieve word variants: su ((sach ky) or (sach y)) nang xa hoi. hieu ve cam ((xuc va) or (truc va)) hanh vi cua tre*.
