Perhaps you should try some spelling variations:
nhung cong » dung cong, thong cong, hang cong
chua xang » chua nang, chuc nang, chu bang
hanh dung » thanh dung, anh dung, hanh dong
hung cong » hung cuong, phung cong, dung cong
dan toan » van toan, dan than, manh toan
toan cau » toan cao, toan ban, toan tap
chu han » chu van

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 ((chua xang) OR (chu han)) - hanh dung luan ((hung cong) OR (nhung cong)) dan toan cau~.
• Adding a wildcard symbol may retrieve word variants: theo ((chua xang) or (chu han)) - hanh dung luan ((hung cong) or (nhung cong)) dan toan cau*.
