Perhaps you should try some spelling variations:
thuat lanh » thuat lap, thuat san
cau trung » cau truong, cac trung, cao trung
lanh lay » thanh lay, lanh dao, hanh lam
lay nang » may nang, day nang, ly nang
trung va » truong va, trang va, trung ha
hieu ve » hieu van
hieu va » lieu va, hieu qua
va hanh » van hanh, va thanh, va danh
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 lay nang x hoi. ((hieu ve) OR (hieu va)) cau trung va hanh vi cua te~.
• Adding a wildcard symbol may retrieve word variants: thuat lanh lay nang x hoi. ((hieu ve) or (hieu va)) cau trung va hanh vi cua te*.
