Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
dam thuc » am thuc, dan thuc, nam thuc
su sach » so sach, vu sach
sach ky » sac ky, sach y, sach ty
minh vi » minh voi, dinh vi, minh va
ma hoi » mai hoi, xa hoi, me hoi
vi cua » vai cua, di cua

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

• Performing a fuzzy search may retrieve terms with similar spellings: su sach ky nang ((ma hoi) OR (ma hoa)). lieu va ((dam thuc) or (cam xuc)) van minh vi cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ky nang ((ma hoi) OR (ma hoa)). lieu va ((dam thuc) OR (cam xuc)) van minh vi cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ky nang ((ma hoi) OR (ma hoa)). lieu va ((dam thuc) or (cam xuc)) van minh vi cua triet*".
