Perhaps you should try some spelling variations:
thuat sach » thuat lanh, thuat san
hieu ve » hieu va, hieu van
hanh va » hang va, hanh vi
cua tre » cua te, cua triet, dua tren
cuu tre » cau tren, cau treo
y nang » ky nang, ly nang, v nang
ve cam » ve cham, ve cac, va cam
luc 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: thuat sach y nang x hoi. hieu ve cam ((luc va) or (duc va)) hanh va ((cua tre) OR (cuu tre))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thuat sach y nang x hoi. hieu ve cam ((luc va) OR (duc va)) hanh va ((cua tre) OR (cuu tre))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuat sach y nang x hoi. hieu ve cam ((luc va) or (duc va)) hanh va ((cua tre) OR (cuu tre))*".
