Perhaps you should try some spelling variations:

cua triet » cua viet, su triet, va triet
phat xuc » chat xuc, phat xuat, phap xu
hieu va » lieu va, hieu qua
va lang » hoa lang
va nang » van nang, da nang, cam nang
doi cua » dai cua, hoi cua
tu cach » tu cac
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: ((tu cach) or (thuat sach)) ky nang x hoi. hieu va phat xuc ((va lang) OR (va nang)) doi cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu cach) OR (thuat sach)) ky nang x hoi. hieu va phat xuc ((va lang) OR (va nang)) doi cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu cach) or (thuat sach)) ky nang x hoi. hieu va phat xuc ((va lang) OR (va nang)) doi cua triet*".
