Perhaps you should try some spelling variations:
phan duc » pham duc, phan tu, phan dau
hanh vai » hanh vi, hanh va, hanh tai
hieu ve » hieu van
hieu va » lieu va, hieu qua
va hanh » van hanh, va thanh, va danh
cua cau » cua cac, cua chu, cua cay
tu sac » tu sach, tu cac, tu san
sac ky » cac ky, sai 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 sac ky nang x hoi. ((hieu ve) OR (hieu va)) phan duc va hanh vai ((cua cu) OR (cua cau))~.
• Adding a wildcard symbol may retrieve word variants: tu sac ky nang x hoi. ((hieu ve) or (hieu va)) phan duc va hanh vai ((cua cu) or (cua cau))*.
