Perhaps you should try some spelling variations:
hanh vai » hanh vi, hanh va, hanh tai
sach ly » sach lo, sach ty, sach hay
cua tre » cua te, cua triet, dua tren
va hanh » van hanh, va thanh, va danh
cam luc » cam xuc, cau luc
hieu ve » hieu va, hieu van
cuu tre » cau tren, cau treo
ve cam » ve cham, ve cac, va cam
luc va » duc va, tuc va, loc va
x hoi » xa hoi, o hoi, x ho

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

• Performing a fuzzy search may retrieve terms with similar spellings: thuoc ((sach ly) OR (sach y)) nang x hoi. hieu ve cam luc va hanh vai ((cua tre) or (cuu tre))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thuoc ((sach ly) OR (sach y)) nang x hoi. hieu ve cam luc va hanh vai ((cua tre) OR (cuu tre))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuoc ((sach ly) OR (sach y)) nang x hoi. hieu ve cam luc va hanh vai ((cua tre) or (cuu tre))*".
