Perhaps you should try some spelling variations:
su sach » so sach, vu sach
hieu ve » hieu va, hieu van
ve chao » ve chat, ve cham, ve cho
va dinh » van dinh, va kinh, vu dinh
va tinh » may tinh
ang xa » lang xa, mang xa, dang xay
vi cua » vai cua, di cua
cua te » cua tu

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach y ang xa hoi. hieu ve chao xu ((va dinh) OR (va tinh)) vi cua te~".
• Adding a wildcard symbol may retrieve word variants: su sach y ang xa hoi. hieu ve chao xu ((va dinh) OR (va tinh)) vi cua te*.
