Perhaps you should try some spelling variations:
tu tuong » tu dong
thanh ve » thanh va, thanh vien, thanh van
sach vu » sach va, sach tu, sach uu
hanh ve » hanh vi, hanh va, hanh kem
xuc van » duc van, luc van, vuc van
tu sach » thu sach, su sach, te sach
vu nang » vuc nang, va nang, vu dang
va cam » va cham, va cac, va cai
va cao » va cac, va co, va dao
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: tu sach vu nang x hoi. hieu ((va cam) or (va cao)) xuc van ((thanh ve) OR (hanh ve)) tu tuong~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach vu nang x hoi. hieu ((va cam) OR (va cao)) xuc van ((thanh ve) OR (hanh ve)) tu tuong.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach vu nang x hoi. hieu ((va cam) or (va cao)) xuc van ((thanh ve) OR (hanh ve)) tu tuong".
• Adding a wildcard symbol may retrieve word variants: tu sach vu nang x hoi. hieu ((va cam) or (va cao)) xuc van ((thanh ve) OR (hanh ve)) tu tuong*.
