Perhaps you should try some spelling variations:
cua viet » ca viet, hoa viet, cua vat
hanh hai » thanh hai, nhanh hai, hang hai
hai cua » thai cua, dai cua, hoi cua
va hanh » van hanh, va thanh, va danh
su sach » so sach, vu sach
cam tuc » cam xuc, nam thuc, dam thuc
hieu va » lieu va, hieu qua
nang xa » nang x, lang xa, nang ma
y nang » ky nang, ly nang, v nang
cam tu » cam thu, nam tu, dam tu

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 xa hoi. hieu va ((((cam tuc) OR (cam tu))) or (am thuc)) va hanh hai cua viet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach y nang xa hoi. hieu va ((((cam tuc) OR (cam tu))) OR (am thuc)) va hanh hai cua viet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach y nang xa hoi. hieu va ((((cam tuc) OR (cam tu))) or (am thuc)) va hanh hai cua viet".
• Adding a wildcard symbol may retrieve word variants: su sach y nang xa hoi. hieu va ((((cam tuc) OR (cam tu))) or (am thuc)) va hanh hai cua viet*.
