Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
hanh thai » nhanh thai, hinh thai, hanh tai
cam duc » cam xuc, cao duc, pham duc
cua tre » cua te, cuu tre, dua tren
va hanh » van hanh, va thanh, va danh
hieu va » lieu va, hieu qua
hieu ve » hieu van
dang xa » dang xay, lang xa, dang ha
ky dang » ky nang, ky danh
hai ky » thai ky, hoi ky, hai ly
su hai » su tai

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

• Performing a fuzzy search may retrieve terms with similar spellings: su hai ky dang xa hoi. ((hieu ve) OR (hieu va)) cam duc va hanh thai ((cua tre) or (cua triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su hai ky dang xa hoi. ((hieu ve) OR (hieu va)) cam duc va hanh thai ((cua tre) OR (cua triet))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su hai ky dang xa hoi. ((hieu ve) OR (hieu va)) cam duc va hanh thai ((cua tre) or (cua triet))*".
