Perhaps you should try some spelling variations:
cua triet » cua viet, va triet
su triet » su viet, su tien, ve triet
hieu ve » hieu va, hieu van
cam tuc » cam xuc, cam tu, nam thuc
va danh » va dinh, va dan, va hanh
danh vi » hanh vi, dinh vi, danh di
su sai » su tai, su hai, su dai
sai ky » sac ky
ve cam » ve cham, ve cac, va cam
tuc va » thuc va, truc va, tuc xa
x hoi » xa hoi, o hoi, 5 hoi

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) OR (x ho)). hieu ve cam tuc 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) OR (x ho)). hieu ve cam tuc 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) OR (x ho)). hieu ve cam tuc va danh vi ((cua triet) or (su triet))*".
