Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
tham soc » cham soc, tham nuoc, thai son
va hanh » van hanh, va thanh, va danh
va tham » van tham, va cham, va thanh
hieu va » lieu va, hieu qua
lang xa » lang ha, dang xay, lang van
sac ky » cac ky
soc va » hoc va, loc va, doc va
cua te » cua tu

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) OR (sai ky)) lang xa hoi. hieu va tham soc va hanh vi ((cua te) or (cua triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sac ky) OR (sai ky)) lang xa hoi. hieu va tham soc va hanh vi ((cua te) OR (cua triet))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sac ky) OR (sai ky)) lang xa hoi. hieu va tham soc va hanh vi ((cua te) or (cua triet))*".
