Perhaps you should try some spelling variations:
va hanh » van hanh, va thanh, va danh
sach ky » sac ky, sach y, sach kem
cua tre » cua te, cuu tre, cua triet
nang xa » nang x, lang xa, nang ma
sach ty » sach y, sach tu, sach thu
va cao » va cac, va co, va dao
xuc va » duc va, tuc va, luc va
vi cua » vai cua, di cua
ve cam » ve cham, ve cac, va cam

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 ky) OR (sach ty)) nang xa hoi. hieu ((ve cam) OR (va cao)) xuc va hanh vi cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach ky) OR (sach ty)) nang xa hoi. hieu ((ve cam) or (va cao)) xuc va hanh vi cua tre~".
• Adding a wildcard symbol may retrieve word variants: te ((sach ky) OR (sach ty)) nang xa hoi. hieu ((ve cam) or (va cao)) xuc va hanh vi cua tre*.
