Perhaps you should try some spelling variations:
cua triet » cua viet, va triet
su triet » su viet, su tien, ve triet
thuc van » thuc vat, thuc dan, thuc va
van hanh » van thanh, ban hanh, van anh
cuu thuc » cuu tac
hieu va » lieu va, hieu qua
hieu ve » hieu van
hanh te » hanh tu, hanh ve, hanh de
nang xa » nang x, lang xa, nang ma
sai ky » sac ky
su sai » su tai, su hai, su dai

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

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