Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
ban thanh » ban hanh, ban hang
va thanh » gia thanh, va tinh, le thanh
cua tre » cua te, cuu tre, dua tren
va hanh » van hanh, va danh, ban hanh
dang ha » dong ha, dung ha, lang ha
ky dang » ky nang, ky danh
sac ky » cac ky, sai ky
ha hoi » hoa hoi, ha noi, xa hoi
soc va » hoc va, loc va, doc va
te sac » te sach, te cac, te san

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