Perhaps you should try some spelling variations:
thanh lai » thanh hai, thanh lap, thanh loi
va triet » va thiet, va trien, ve triet
va thanh » gia thanh, ban thanh, va tinh
nam thuc » nam thuoc, am thuc, nam thu
cam truc » cau truc, nam truc, lam truoc
sach ky » sac ky, sach y, sach ty
nang ro » nang co, nang ho, nang ra
tu sach » thu sach, su sach, te sach
nang o » nang co, nang ho, nang x
lai va » loai va, mai va, dai va

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

• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ky ((nang o) OR (nang ro)) lai. lieu va ((cam truc) or (nam thuc)) va thanh lai va triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ky ((nang o) OR (nang ro)) lai. lieu va ((cam truc) OR (nam thuc)) va thanh lai va triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ky ((nang o) OR (nang ro)) lai. lieu va ((cam truc) or (nam thuc)) va thanh lai va triet".
• Adding a wildcard symbol may retrieve word variants: tu sach ky ((nang o) OR (nang ro)) lai. lieu va ((cam truc) or (nam thuc)) va thanh lai va triet*.
