Perhaps you should try some spelling variations:
luan trong » quan trong, luat trong, luan tuong
hanh dung » thanh dung, anh dung, hanh dong
van thanh » ban thanh
theo chu » theo chieu, cho chu, chao chu
chu xanh » chu manh, chieu xanh, chua xang
dan toan » van toan, dan than, manh toan
van tuan » van quan, van ban, anh 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 trong cong ((dan toan) OR (((van thanh) OR (van tuan)))) cao~.
• Adding a wildcard symbol may retrieve word variants: theo chu xanh - hanh dung luan trong cong ((dan toan) or (((van thanh) or (van tuan)))) cao*.
