Perhaps you should try some spelling variations:
nhanh lang » nhanh quang, nhanh thang, nhan dang
dung cong » dung trong
anh tang » anh bang, anh dang, anh nang
cua dung » cua dang, cua dong, qua dung
cong dan » cong san, cong tan, huong dan
dan than » dan chan, ban than, van than
than cau » toan cau, phan cau, than cap
chu van » cuu 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 han) OR (chu van)) - ((nhanh lang) OR (anh tang)) cua dung cong dan than cau~.
• Adding a wildcard symbol may retrieve word variants: theo ((chu han) or (chu van)) - ((nhanh lang) or (anh tang)) cua dung cong dan than cau*.
