Perhaps you should try some spelling variations:
nhung cong » dung cong, hang cong, nhung don
thong cong » trong cong, tong cong, thong thong
doan tien » doan thien, doanh tien, toan tien
hanh dinh » thanh dinh, hinh dinh, hanh tinh
dinh thi » dinh tri
dan toan » van toan, dan than, manh toan
toan cau » toan cao, toan ban, toan tap

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "doan tien thinh - hanh dinh thi ((nhung cong) OR (thong cong)) dan toan cau~".
• Adding a wildcard symbol may retrieve word variants: doan tien thinh - hanh dinh thi ((nhung cong) OR (thong cong)) dan toan cau*.
