Perhaps you should try some spelling variations:
nhung cong » dung cong, thong cong, hang cong
cong manh » cong danh, duong manh, cong thanh
theo chu » theo chieu, cho chu, chao chu
chu xang » chua xang, chu bang, chuc nang
anh tang » anh bang, anh dang, anh sang
anh nang » ganh nang, anh bang, anh dang
toan cau » toan cao, toan tap, toan tai
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: theo chu xang - ((anh tang) OR (anh nang)) va nhung cong manh ((toan cau) OR (toan ban))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chu xang - ((anh tang) OR (anh nang)) va nhung cong manh ((toan cau) or (toan ban))~".
• Adding a wildcard symbol may retrieve word variants: theo chu xang - ((anh tang) OR (anh nang)) va nhung cong manh ((toan cau) or (toan ban))*.
