Perhaps you should try some spelling variations:
danh lien » danh kien, doanh tien, doanh vien
danh dien » dinh dien, danh kien, nganh dien
cu triet » cua triet, cau triet, su triet
te sach » toc sach
sach ky » sac ky, sach y, sach ty
ve chat » va chat, van chat
ve cam » ve cham, ve cac, va cam
x hoi » xa hoi, o hoi, x ho

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 ky nang x hoi. hieu ((ve cam) or (ve chat)) thuc vat ((danh dien) OR (danh lien)) cu triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky nang x hoi. hieu ((ve cam) OR (ve chat)) thuc vat ((danh dien) OR (danh lien)) cu triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky nang x hoi. hieu ((ve cam) or (ve chat)) thuc vat ((danh dien) OR (danh lien)) cu triet*".
