Perhaps you should try some spelling variations:
van thanh » ban thanh, van tuan
ve triet » va trien, su triet
va triet » va thiet, va trien, cua triet
thanh vi » hanh vi, thanh va, thanh ve
xuc van » duc van, luc van, vuc van
tu sach » thu sach, su sach, te sach
hieu va » lieu va, hieu qua
ty nang » ky nang, ty hang, ly nang
ma hoi » mai hoi, xa hoi, ma hoa
va cam » va cham, va cac, va cao

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 nang) or (ty xang)) ma hoi. hieu va cam xuc van thanh vi ((va triet) OR (ve triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ((ty nang) OR (ty xang)) ma hoi. hieu va cam xuc van thanh vi ((va triet) OR (ve triet))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ((ty nang) or (ty xang)) ma hoi. hieu va cam xuc van thanh vi ((va triet) OR (ve triet))*".
