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