Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
van hanh » van thanh, ban hanh, van anh
va thanh » ban thanh, va tinh, le thanh
su sach » so sach, vu sach
y nang » ky nang, ly nang, v nang
va cam » va cham, va cac, va cao
vi cua » vai cua, di cua

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

• Performing a fuzzy search may retrieve terms with similar spellings: su sach y nang x ho. lieu va cam xuc ((((va thanh) OR (gia thanh))) or (van hanh)) vi cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach y nang x ho. lieu va cam xuc ((((va thanh) OR (gia thanh))) OR (van hanh)) vi cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach y nang x ho. lieu va cam xuc ((((va thanh) OR (gia thanh))) or (van hanh)) vi cua triet".
• Adding a wildcard symbol may retrieve word variants: su sach y nang x ho. lieu va cam xuc ((((va thanh) OR (gia thanh))) or (van hanh)) vi cua triet*.
