Perhaps you should try some spelling variations:
cua thuong » cua truong, cua phuong, cua huong
thanh dung » thanh duong, thanh tung, thanh hung
tieu xanh » tieu danh, chieu xanh, dieu hanh
hanh dung » anh dung, hanh dong, manh dung
ca thuong » cao thuong, va thuong, cp thuong
con dan » cong dan, co dan, con ban
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 tieu xanh - ((hanh dung) OR (thanh dung)) ((cua thuong) OR (ca thuong)) con dan van ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo tieu xanh - ((hanh dung) or (thanh dung)) ((cua thuong) OR (ca thuong)) con dan van ban~".
• Adding a wildcard symbol may retrieve word variants: theo tieu xanh - ((hanh dung) or (thanh dung)) ((cua thuong) OR (ca thuong)) con dan van ban*.
