Perhaps you should try some spelling variations:
nhung cong » dung cong, thong cong, hang cong
mang luan » hang luan, mong luan, dung luan
tang luan » dung luan
bang luan » hang luan, dung luan, tong luan
cong vinh » cong trinh, trong vinh, cong viec
vinh toan » tinh toan, hinh toan, minh toan
theo chu » theo chieu, cho chu, chao chu
chu xanh » chu manh, chieu xanh, chua xang
toan cau » toan cao, toan ban, toan tap

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: theo chu xanh - nhanh ((((mang luan) OR (tang luan))) OR (bang luan)) nhung cong vinh toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chu xanh - nhanh ((((mang luan) OR (tang luan))) or (bang luan)) nhung cong vinh toan cau~".
• Adding a wildcard symbol may retrieve word variants: theo chu xanh - nhanh ((((mang luan) OR (tang luan))) or (bang luan)) nhung cong vinh toan cau*.
