Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
hanh moi » thanh moi, hanh noi, hanh mot
moi cua » hoi cua, doi cua, moi quan
va hanh » van hanh, va thanh, va danh
thuc va » thuc vat, thuc dan, thuc day
tu sach » thu sach, su sach, te sach
lang ha » long ha
lang xa » dang xay, lang van
he nam » ha nam, nghe nam
ve nam » va nam, le nam, te nam

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 ((lang xa) or (lang ha)) hoi. hieu ((ve nam) OR (he nam)) thuc va hanh moi cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach y ((lang xa) OR (lang ha)) hoi. hieu ((ve nam) OR (he nam)) thuc va hanh moi cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach y ((lang xa) or (lang ha)) hoi. hieu ((ve nam) OR (he nam)) thuc va hanh moi cua triet*".
