Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
va thanh » gia thanh, ban thanh, va tinh
ban hanh » ban hang
su sach » so sach, vu sach
ty nang » ky nang, ty hang, ly nang
hieu ve » hieu va, hieu van
vai cua » dai cua, hai cua, lai cua
ve cam » ve cham, ve cac, va cam

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 ((ty nang) OR (ty xang)) xa hoi. hieu ve cam xuc ((va thanh) or (ban hanh)) vai cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ((ty nang) OR (ty xang)) xa hoi. hieu ve cam xuc ((va thanh) OR (ban hanh)) vai cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ((ty nang) OR (ty xang)) xa hoi. hieu ve cam xuc ((va thanh) or (ban hanh)) vai cua triet".
• Adding a wildcard symbol may retrieve word variants: su sach ((ty nang) OR (ty xang)) xa hoi. hieu ve cam xuc ((va thanh) or (ban hanh)) vai cua triet*.
