Perhaps you should try some spelling variations:
cua triet » su triet, va triet
cua viet » ca viet, hoa viet, cua vat
tham xuc » tham nuoc, tham thuc, pham duc
van hanh » van thanh, ban hanh, van anh
hanh di » hanh vi, hanh de, hang di
xuc van » duc van, luc van, vuc van
va tham » van tham, va cham, va thanh
lang ha » long ha
sang ky » sang kyo, dang ky, tang ky
san ky » van ky, dan ky, ban ky

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

• Performing a fuzzy search may retrieve terms with similar spellings: tu ((san ky) or (sang ky)) lang ha noi. lieu va tham xuc van hanh di ((cua triet) OR (cua viet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((san ky) OR (sang ky)) lang ha noi. lieu va tham xuc van hanh di ((cua triet) OR (cua viet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((san ky) or (sang ky)) lang ha noi. lieu va tham xuc van hanh di ((cua triet) OR (cua viet))".
• Adding a wildcard symbol may retrieve word variants: tu ((san ky) or (sang ky)) lang ha noi. lieu va tham xuc van hanh di ((cua triet) OR (cua viet))*.
