Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
van tham » van thanh, van tuan, van chat
danh vi » hanh vi, dinh vi, danh di
va danh » va dinh, va dan, va hanh
tu sach » thu sach, su sach, te sach
lang xa » lang ha, dang xay, lang van
nang xa » nang x, nang ma, mang xa
va cham » va chat, va tham
soc va » hoc va, loc va, doc va
vi cua » vai cua, di cua

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: tu sach y ((nang xa) OR (lang xa)) hoi. hieu ((va cham) or (van tham)) soc va danh vi cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach y ((nang xa) OR (lang xa)) hoi. hieu ((va cham) OR (van tham)) soc va danh vi cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach y ((nang xa) OR (lang xa)) hoi. hieu ((va cham) or (van tham)) soc va danh vi cua triet*".
