Perhaps you should try some spelling variations:
tu sach » thu sach, su sach, te sach
sach ty » sach y, sach tu, sach thu
vai cua » dai cua, hai cua, lai cua
va tinh » may tinh
va danh » va dinh, va dan, va hanh
cua tuc » cua duc, cua tu, cua thuoc
hieu ve » hieu van
hieu va » lieu va, hieu qua
ty nang » ky nang, ty xang, ty hang
x hoi » xa hoi, o hoi, x ho

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

• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ty nang x hoi. ((hieu ve) OR (hieu va)) cam xuc ((va danh) OR (va tinh)) vai cua tuc~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ty nang x hoi. ((hieu ve) OR (hieu va)) cam xuc ((va danh) or (va tinh)) vai cua tuc~".
• Adding a wildcard symbol may retrieve word variants: tu sach ty nang x hoi. ((hieu ve) OR (hieu va)) cam xuc ((va danh) or (va tinh)) vai cua tuc*.
