Perhaps you should try some spelling variations:
cua triet » cua viet, va triet
su triet » su viet, su tien, ve triet
thuc dan » thuc hanh, hoc dan
hanh ca » hanh cac, hanh cat, hanh cua
vu sach » vu bach, su sach, vu khach
sach ky » sac ky, sach y, sach ty
hieu ve » hieu va, hieu van
lang xa » lang ha, dang xay, lang van
ky lang » ky nang, ky dang, ky tang
ve am » va am

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

• Performing a fuzzy search may retrieve terms with similar spellings: vu sach ky lang xa hoi. hieu ve am ((thuc dan) or (thuc vat)) hanh ca ((cua triet) OR (su triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu sach ky lang xa hoi. hieu ve am ((thuc dan) OR (thuc vat)) hanh ca ((cua triet) OR (su triet))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sach ky lang xa hoi. hieu ve am ((thuc dan) or (thuc vat)) hanh ca ((cua triet) OR (su triet))*".
