Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
qua cham » qua hai, qua cac, va cham
cham xuc » cam xuc, chat xuc, cham soc
van hanh » van thanh, ban hanh, van anh
vu sach » vu bach, su sach, vu khach
sach ky » sac ky, sach y, sach ty
va hanh » va thanh, ban hanh, dao hanh
va danh » va dinh, va dan, dia danh
vai cua » dai cua, hai cua, lai cua
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: vu sach ky nang x hoi. hieu qua cham xuc ((((va hanh) OR (va danh))) or (van hanh)) vai cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu sach ky nang x hoi. hieu qua cham xuc ((((va hanh) OR (va danh))) OR (van hanh)) vai cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sach ky nang x hoi. hieu qua cham xuc ((((va hanh) OR (va danh))) or (van hanh)) vai cua triet".
• Adding a wildcard symbol may retrieve word variants: vu sach ky nang x hoi. hieu qua cham xuc ((((va hanh) OR (va danh))) or (van hanh)) vai cua triet*.
