Perhaps you should try some spelling variations:
hanh vai » hanh vi, hanh va, hanh tai
sach ty » sach tu, sach thu, xach tay
nang xa » nang x, lang xa, nang ma
thi van » thi lan, thi hanh, thi nang
van cam » van nam, van lam, van cau
vai cua » dai cua, hai cua, lai cua
cua tre » cua te, cuu tre, cua triet
xuc va » duc va, tuc va, luc va

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: tu ((sach ty) OR (sach y)) nang xa hoi. thi van cam ((xuc va) or (hoc dan)) hanh vai cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach ty) OR (sach y)) nang xa hoi. thi van cam ((xuc va) OR (hoc dan)) hanh vai cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach ty) OR (sach y)) nang xa hoi. thi van cam ((xuc va) or (hoc dan)) hanh vai cua tre*".
