Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
thanh tran » thanh trang, thanh toan, thanh tuan
thanh tra » thanh toan, thanh hoa
nang dung » dang dung, nang dong, rang dung
dung cong » dung trong
cong van » cong vang, cong san, song van
van quan » van ban
quan tap » quan tai, quan lap, quan tam

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: ho ((chieu xanh) OR (chinh sach)) - ((thanh tran) OR (thanh tra)) nang dung cong van quan tap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu xanh) or (chinh sach)) - ((thanh tran) OR (thanh tra)) nang dung cong van quan tap~".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu xanh) or (chinh sach)) - ((thanh tran) OR (thanh tra)) nang dung cong van quan tap*.
