Perhaps you should try some spelling variations:
cua triet » cua viet, su triet
hanh doi » thanh doi, hanh noi, hang doi
va triet » va thiet, va trien, ve triet
ky lang » ky nang, ky dang, ky tang
lang xa » lang ha, dang xay, lang van
va cham » va chat, va tham
xuc van » luc van, vuc van, xuc ban
duc van » duc va, duc tan, duc manh
tu san » thu san, tu ban, tu can
san ky » sang ky, van ky, dan 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 lang xa hoi. lieu va cham ((xuc van) or (duc van)) hanh doi ((cua triet) OR (va triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu san ky lang xa hoi. lieu va cham ((xuc van) OR (duc van)) hanh doi ((cua triet) OR (va triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu san ky lang xa hoi. lieu va cham ((xuc van) or (duc van)) hanh doi ((cua triet) OR (va triet))".
• Adding a wildcard symbol may retrieve word variants: tu san ky lang xa hoi. lieu va cham ((xuc van) or (duc van)) hanh doi ((cua triet) OR (va triet))*.
