Perhaps you should try some spelling variations:
hieu van » hieu va, thien van, lieu va
duc tre » duoc tren, duc tien
va dinh » van dinh, va kinh, va tinh
cuc tre » cua tre, cuu tre, cuc thue
va hanh » van hanh, va thanh, va danh
cau xuc » cam xuc, cau luc, cau truc
van cau » van dau, van hau, van chat
nang xa » nang x, lang xa, nang ma
sac ky » cac ky, sai ky
su sac » su sach, su cac, su xac

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

• Performing a fuzzy search may retrieve terms with similar spellings: su sac ky nang xa hoi. hieu van cau xuc ((va hanh) or (va dinh)) thi ((cuc tre) OR (duc tre))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sac ky nang xa hoi. hieu van cau xuc ((va hanh) OR (va dinh)) thi ((cuc tre) OR (duc tre)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sac ky nang xa hoi. hieu van cau xuc ((va hanh) or (va dinh)) thi ((cuc tre) OR (duc tre))".
• Adding a wildcard symbol may retrieve word variants: su sac ky nang xa hoi. hieu van cau xuc ((va hanh) or (va dinh)) thi ((cuc tre) OR (duc tre))*.
