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
ban hang » ngan hang
nam xua » nam cua, nam mua, nam qua
te sach » toc sach
sach ky » sac ky, sach y, sach ty
nam xuc » cam xuc, nam thuc, nam duoc
tang xa » trang xa, tang ma, lang xa
ky tang » ky nang, ky dang, kho tang

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 tang xa hoi. thien van ((nam xuc) OR (nam xua)) ban hang va ((cua triet) or (su triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky tang xa hoi. thien van ((nam xuc) OR (nam xua)) ban hang va ((cua triet) OR (su triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky tang xa hoi. thien van ((nam xuc) OR (nam xua)) ban hang va ((cua triet) or (su triet))".
• Adding a wildcard symbol may retrieve word variants: te sach ky tang xa hoi. thien van ((nam xuc) OR (nam xua)) ban hang va ((cua triet) or (su triet))*.
