Perhaps you should try some spelling variations:
hanh vai » hanh vi, hanh va, hanh tai
su sach » so sach, vu sach
vai cua » dai cua, hai cua, lai cua
va hanh » van hanh, va thanh, va danh
va tham » van tham, va cham, va thanh
ty nang » ky nang, ty hang, ly nang
loc va » hoc va, luc va
cua te » cua tu

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 ((va tham) or (va cac)) loc va hanh vai cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ((ty nang) OR (ty xang)) xa hoi. hieu ((va tham) OR (va cac)) loc va hanh vai cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ((ty nang) OR (ty xang)) xa hoi. hieu ((va tham) or (va cac)) loc va hanh vai cua te*".
