Perhaps you should try some spelling variations:
thong cong » trong cong, tong cong, thong thong
hanh dung » thanh dung, anh dung, hanh dong
hang cong » dang cong, hang nong, bang cong
theo chu » theo chieu, cho chu, chao chu
chu xanh » chu manh, chieu xanh, chua xang
van tan » van tuan, van ban, van thanh
van tai » von tai, van tuan

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 - hanh dung luan ((thong cong) OR (hang cong)) ((van tan) OR (van tai)) cau~.
• Adding a wildcard symbol may retrieve word variants: theo chu xanh - hanh dung luan ((thong cong) or (hang cong)) ((van tan) or (van tai)) cau*.
