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