Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
va danh » va dinh, va dan, dia danh
cua tre » cua te, cuu tre, dua tren
va hanh » van hanh, va thanh, ban hanh
hieu ve » hieu va, hieu van
cam tuc » cam xuc, cam tu, nam thuc
sac ky » cac ky, sai ky
ve cam » ve cham, ve cac, va cam
te sac » te sach, te cac, te san
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: te sac ky nang x hoi. hieu ve cam tuc ((va hanh) or (va danh)) vi ((cua tre) OR (cua triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sac ky nang x hoi. hieu ve cam tuc ((va hanh) OR (va danh)) vi ((cua tre) OR (cua triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sac ky nang x hoi. hieu ve cam tuc ((va hanh) or (va danh)) vi ((cua tre) OR (cua triet))".
• Adding a wildcard symbol may retrieve word variants: te sac ky nang x hoi. hieu ve cam tuc ((va hanh) or (va danh)) vi ((cua tre) OR (cua triet))*.
