Perhaps you should try some spelling variations:
chua xang » chua nang, chuc nang, chu bang
tang quan » tang luan, nang quan, tong quan
dung cong » dung trong
chu xanh » chu manh, chieu xanh, chuc danh
tang qua » tang cua, tang quy, tang quang
cong dan » cong san, cong tan, huong dan
dan than » dan chan, ban than, van than
than cap » khan cap, thanh lap, thanh cac

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 (chua xang)) - hanh ((tang qua) OR (tang quan)) dung cong dan than cap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chu xanh) or (chua xang)) - hanh ((tang qua) OR (tang quan)) dung cong dan than cap~".
• Adding a wildcard symbol may retrieve word variants: theo ((chu xanh) or (chua xang)) - hanh ((tang qua) OR (tang quan)) dung cong dan than cap*.
