Perhaps you should try some spelling variations:
nhung cong » dung cong, thong cong, hang cong
chiet tach » chieu sach
chu xanh » chu manh, chieu xanh, chua xang
anh tang » anh dang, anh nang, anh sang
anh bang » anh hoang, anh quang, tinh bang
cong dan » cong san, cong tan, huong dan
dan toan » van toan, dan than, manh toan
toan cao » toan ban, toan tap

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 (chiet tach)) - ((anh tang) OR (anh bang)) va nhung cong dan toan cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chu xanh) or (chiet tach)) - ((anh tang) OR (anh bang)) va nhung cong dan toan cao~".
• Adding a wildcard symbol may retrieve word variants: theo ((chu xanh) or (chiet tach)) - ((anh tang) OR (anh bang)) va nhung cong dan toan cao*.
