Perhaps you should try some spelling variations:
thuat lanh » thuat lap, thuat san
lanh ky » hanh ky, nganh ky, thanh ky
hieu ve » hieu van
hieu va » lieu va, hieu qua
suc va » tuc va, luc va, soc va
vi cua » vai cua, di cua
cua te » cua tu
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: thuat lanh ky nang x hoi. ((hieu ve) OR (hieu va)) cao ((suc va) OR (duc va)) hanh vi cua te~.
• Adding a wildcard symbol may retrieve word variants: thuat lanh ky nang x hoi. ((hieu ve) or (hieu va)) cao ((suc va) or (duc va)) hanh vi cua te*.
