Perhaps you should try some spelling variations:
phan duc » pham duc, phan tu, phan dau
va thanh » gia thanh, ban thanh, va tinh
hieu ve » hieu va, hieu van
ve phan » va phan, ke phan, ve phat
va hanh » van hanh, va danh, ban hanh
cua cau » cua cac, cua chu, cua cay
tu san » thu san, tu ban, tu can
san ky » sang ky, van ky, dan ky
cua cu » cua chu, cua su, cua co
x hoi » xa hoi, o hoi, x ho

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: tu san ky nang x hoi. hieu ve phan duc ((va hanh) OR (va thanh)) vai ((cua cu) OR (cua cau))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu san ky nang x hoi. hieu ve phan duc ((va hanh) or (va thanh)) vai ((cua cu) OR (cua cau))~".
• Adding a wildcard symbol may retrieve word variants: tu san ky nang x hoi. hieu ve phan duc ((va hanh) or (va thanh)) vai ((cua cu) OR (cua cau))*.
