Perhaps you should try some spelling variations:
va thanh » gia thanh, ban thanh, va tinh
hieu van » hieu va, thien van, lieu va
va hanh » van hanh, va danh, ban hanh
cao hoi » cau hoi, co hoi, cao hoc
van cau » van dau, van hau, van chat
cau xuc » cam xuc, cau luc, cau truc
cuu tre » cua tre, cau tren, cau treo
su sac » su sach, su cac, su xac
sac ky » cac ky, sai ky
cua te » cua 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 sac ky nang cao hoi. hieu van cau xuc ((va hanh) OR (va thanh)) hai ((cuu tre) or (cua te))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sac ky nang cao hoi. hieu van cau xuc ((va hanh) OR (va thanh)) hai ((cuu tre) OR (cua te)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sac ky nang cao hoi. hieu van cau xuc ((va hanh) OR (va thanh)) hai ((cuu tre) or (cua te))".
• Adding a wildcard symbol may retrieve word variants: su sac ky nang cao hoi. hieu van cau xuc ((va hanh) OR (va thanh)) hai ((cuu tre) or (cua te))*.
