Perhaps you should try some spelling variations:
su triet » su viet, su tien, ve triet
tai lang » tai cong, thi lan, va lang
hanh lai » hanh lam, hanh tai, thanh lap
va hanh » van hanh, va thanh, va danh
va tham » van tham, va cham, va thanh
tu sach » thu sach, su sach, te sach
tai san » tai ngan
tuc va » thuc va, truc va, tuc xa
va cao » va cac, va co, va dao

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 ((tai lang) OR (tai san)) xa hoi. hieu ((va cao) or (va tham)) tuc va hanh lai su triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ((tai lang) OR (tai san)) xa hoi. hieu ((va cao) OR (va tham)) tuc va hanh lai su triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ((tai lang) OR (tai san)) xa hoi. hieu ((va cao) or (va tham)) tuc va hanh lai su triet".
• Adding a wildcard symbol may retrieve word variants: tu sach ((tai lang) OR (tai san)) xa hoi. hieu ((va cao) or (va tham)) tuc va hanh lai su triet*.
