Perhaps you should try some spelling variations:
cua triet » su triet, va triet
hieu van » thien van, lieu va, hieu ve
danh tai » doanh tai, dinh tai, hanh tai
cua viet » ca viet, hoa viet, cua vat
tu sach » thu sach, su sach, te sach
nang xa » nang x, lang xa, nang ma
hieu va » lieu va, hieu qua
cau xuc » cam xuc, cau luc, cau truc
va danh » va dinh, va dan, va hanh
y nang » ky nang, ly nang, v nang
xuc va » duc va, tuc va, luc va

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 y nang xa hoi. ((hieu van) OR (hieu va)) cau xuc va danh tai ((cua triet) OR (cua viet))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach y nang xa hoi. ((hieu van) OR (hieu va)) cau xuc va danh tai ((cua triet) or (cua viet))~".
• Adding a wildcard symbol may retrieve word variants: tu sach y nang xa hoi. ((hieu van) OR (hieu va)) cau xuc va danh tai ((cua triet) or (cua viet))*.
