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