Perhaps you should try some spelling variations:
cua triet » cua viet, va triet
thien van » thi van
su triet » su viet, su tien, ve triet
dang xay » dang van, van xay
danh vai » danh sai, danh va, doanh van
va danh » va dinh, va dan, va hanh
te sach » toc sach
truc va » thuc va, thuc vat, trung va
van cau » van dau, van hau, van chat

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

• Performing a fuzzy search may retrieve terms with similar spellings: te sach y ((nang x) or (dang xay)) hoi. thien van cau truc va danh vai ((cua triet) OR (su triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach y ((nang x) OR (dang xay)) hoi. thien van cau truc va danh vai ((cua triet) OR (su triet))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y ((nang x) or (dang xay)) hoi. thien van cau truc va danh vai ((cua triet) OR (su triet))*".
