Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
hanh moi » thanh moi, hanh noi, hanh mot
thuc day » thuc dan, thuc vat
lang xa » lang ha, dang xay, lang van
hieu ve » hieu va, hieu van
thuc va » thuc vat, thuc dan
nang xa » nang x, nang ma, mang xa
moi cua » hoi cua, doi cua, moi quan
tu sach » thu sach, su sach, te sach
ve nam » he nam, va nam, le 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 ((nang xa) or (lang xa)) hoi. hieu ve nam ((thuc va) OR (thuc day)) hanh moi 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 ve nam ((thuc va) OR (thuc day)) hanh moi 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 ve nam ((thuc va) OR (thuc day)) hanh moi cua triet*".
