Perhaps you should try some spelling variations:
cua triet » cua viet, va triet
su triet » su viet, su tien, ve triet
sau trai » sau tai, sau dai, au tram
va danh » va dinh, va dan, va hanh
danh vi » hanh vi, dinh vi, danh di
su trai » su tai, su tri, su troi
hieu ve » hieu va, hieu van
cac thu » cach thuc, cac thoi
ve cac » va cac, vien cac
thu va » thuc va, thue va, tu va
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 trai) OR (sau trai)) ky nang x hoi. hieu ve cac thu va danh vi ((cua triet) or (su triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((su trai) OR (sau trai)) ky nang x hoi. hieu ve cac thu va danh vi ((cua triet) OR (su triet))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su trai) OR (sau trai)) ky nang x hoi. hieu ve cac thu va danh vi ((cua triet) or (su triet))*".
