Perhaps you should try some spelling variations:
va truyen » hoa truyen, co truyen, di truyen
thanh vai » thanh hai, thanh van, thanh tai
va triet » va thiet, va trien, ve triet
va thanh » gia thanh, ban thanh, va tinh
su sach » so sach, vu sach
hieu ve » hieu va, hieu van
ly nang » ky nang, ly hang, ly vang
cau luc » cau truc, cau phuc
ve cau » ke cau, va cau, ve cac
y nang » ky nang, v nang, may nang
luc va » duc va, tuc va, loc va

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

• Performing a fuzzy search may retrieve terms with similar spellings: su sach ((y nang) OR (ly nang)) xa hoi. hieu ve cau luc va thanh vai ((va triet) or (va truyen))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ((y nang) OR (ly nang)) xa hoi. hieu ve cau luc va thanh vai ((va triet) OR (va truyen)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ((y nang) OR (ly nang)) xa hoi. hieu ve cau luc va thanh vai ((va triet) or (va truyen))".
• Adding a wildcard symbol may retrieve word variants: su sach ((y nang) OR (ly nang)) xa hoi. hieu ve cau luc va thanh vai ((va triet) or (va truyen))*.
