Perhaps you should try some spelling variations:
thanh vai » thanh hai, thanh van, thanh tai
ban thanh » ban hanh, ban hang
ve triet » va trien, su triet
hieu van » hieu va, thien van, lieu va
cua tre » cua te, cuu tre, cua triet
xuc ban » duc ban, cuc ban, quoc ban
su sach » so sach
mang xa » lang xa, mang may, dang xay
ty mang » ty xang, ty hang, tin mang
vu sach » vu bach, vu khach
van cam » van nam, van lam, van cau

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

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