Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
thu sach » tu sach, thuat sach, thuoc sach
than cua » nhan cua, thai cua, ban cua
sach ky » sac ky, sach y, sach ty
nang xa » nang x, lang xa, nang ma
hieu va » lieu va, hieu qua
va vanh » va hanh, va anh, va banh
va danh » va dinh, va dan, va hanh
va cam » va cham, va cac, va cao

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

• Performing a fuzzy search may retrieve terms with similar spellings: thu sach ky nang xa hoi. hieu va cam xuc ((((va vanh) OR (va danh))) or (va van)) than cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach ky nang xa hoi. hieu va cam xuc ((((va vanh) OR (va danh))) OR (va van)) than cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach ky nang xa hoi. hieu va cam xuc ((((va vanh) OR (va danh))) or (va van)) than cua triet".
• Adding a wildcard symbol may retrieve word variants: thu sach ky nang xa hoi. hieu va cam xuc ((((va vanh) OR (va danh))) or (va van)) than cua triet*.
