Perhaps you should try some spelling variations:
nhung cong » dung cong, thong cong, hang cong
luan nhung » luan chung, luan hung, quan nhung
chua nang » chuc nang, chua xang, kha nang
hanh dung » thanh dung, anh dung, hanh dong
chu xanh » chu manh, chieu xanh, chua xang
dan than » dan chan, ban than, van than
van toan » van tuan, van tan, van thanh

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