Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
thuc van » thuc dan, thuc va, thuc hanh
nang xa » nang x, lang xa, nang ma
hieu ve » hieu va, hieu van
hanh ve » hanh vi, hanh va, hanh kem
su sai » su tai, su hai, su dai
sai ky » sac ky
ve cua » le cua, de cua, te cua

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 (lieu va)) cau ((thuc van) OR (thuc vat)) hanh ve cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sai ky nang xa hoi. ((hieu ve) OR (lieu va)) cau ((thuc van) OR (thuc vat)) hanh ve cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sai ky nang xa hoi. ((hieu ve) or (lieu va)) cau ((thuc van) OR (thuc vat)) hanh ve cua triet*".
