Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
thu vien » thu hien, thu dien, thuc hien
van hanh » van thanh, ban hanh, van anh
vien dai » hien dai
sach ty » sach y, sach tu, sach thu
dai xuc » dai xu, dai luoc, dai thuc
va hanh » va thanh, va danh, ban hanh
sai ky » sac ky
va cua » va chua, via cua, ca cua
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 ty) or (sai ky)) nang x hoi. thu vien dai xuc ((va hanh) OR (van hanh)) va cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach ty) OR (sai ky)) nang x hoi. thu vien dai xuc ((va hanh) OR (van hanh)) va cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach ty) or (sai ky)) nang x hoi. thu vien dai xuc ((va hanh) OR (van hanh)) va cua triet*".
