Perhaps you should try some spelling variations:
cong thanh » dong thanh, cong trinh, cong tan
nhung cong » dung cong, thong cong, hang cong
lanh manh » lanh tranh, lan anh, anh anh
cua nhung » va nhung
ho trieu » mot trieu, 25 trieu, 30 trieu
van manh » van minh, van anh, van hanh
toan cao » toan tap
toan ban » van ban

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: ho trieu tinh - ((lanh manh) OR (van manh)) cua nhung cong thanh ((toan cao) OR (toan ban))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho trieu tinh - ((lanh manh) OR (van manh)) cua nhung cong thanh ((toan cao) or (toan ban))~".
• Adding a wildcard symbol may retrieve word variants: ho trieu tinh - ((lanh manh) OR (van manh)) cua nhung cong thanh ((toan cao) or (toan ban))*.
