Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
lieu tan » lieu tai, lieu van, lieu ban
sach ty » sach y, sach tu, sach thu
so sach » so sanh, bo sach, co sach
xang xa » lang xa, mang xa, dang xay
tan ngu » han ngu, thanh ngu, trang ngu
ang xa » lang xa, mang xa, dang xay
va dan » ca dan, va dao, va dap
va dau » va dao
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: so sach ty ((xang xa) OR (ang xa)) hoi. lieu tan ngu tuc ((va dan) or (va dau)) vi cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: so sach ty ((xang xa) OR (ang xa)) hoi. lieu tan ngu tuc ((va dan) OR (va dau)) vi cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so sach ty ((xang xa) OR (ang xa)) hoi. lieu tan ngu tuc ((va dan) or (va dau)) vi cua triet".
• Adding a wildcard symbol may retrieve word variants: so sach ty ((xang xa) OR (ang xa)) hoi. lieu tan ngu tuc ((va dan) or (va dau)) vi cua triet*.
