Perhaps you should try some spelling variations:
cua triet » cua viet, va triet
su triet » su viet, su tien, ve triet
truc va » thuc va, thuc vat, trung va
hieu ve » hieu va, hieu van
danh vi » hanh vi, dinh vi, danh di
su sai » su tai, su hai, su dai
sai ky » sac ky
tuc va » thuc va, tuc xa, duc va
ve cam » ve cham, ve cac, va cam
x hoi » xa hoi, o hoi, x ho

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 x hoi. hieu ve cam ((tuc va) OR (truc va)) danh vi ((cua triet) or (su triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sai ky nang x hoi. hieu ve cam ((tuc va) OR (truc va)) danh vi ((cua triet) OR (su triet))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sai ky nang x hoi. hieu ve cam ((tuc va) OR (truc va)) danh vi ((cua triet) or (su triet))*".
