Perhaps you should try some spelling variations:
thanh trung » thanh tung
hanh dung » thanh dung, anh dung, hanh dong
qua trong » quan trong, qua trinh, qua song
theo chu » theo chieu, cho chu, chao chu
chu manh » ho manh, chu han, chu van
cong dan » cong san, cong tan, huong dan
dan van » dang van, doan van, dao 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 chu manh - ((hanh dung) OR (thanh trung)) qua trong cong dan van ban~.
• Adding a wildcard symbol may retrieve word variants: theo chu manh - ((hanh dung) or (thanh trung)) qua trong cong dan van ban*.
