Perhaps you should try some spelling variations:
thanh thuong » thanh huong, thanh chuong, thanh phuong
thanh tuong » thanh tung, thanh huong, thanh cuong
chieu xanh » chieu sach, chieu sang, chieu tinh
duong cong » dung cong, luong cong, duong trong
va duong » van duong, va tuong, va huong
cong van » cong vang, cong san, song van
van toan » van tuan, van tan, van thanh
toan cao » toan ban, toan tap

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: ho ((chieu xanh) or (chinh sach)) - ((thanh tuong) OR (thanh thuong)) va duong cong van toan cao~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu xanh) OR (chinh sach)) - ((thanh tuong) OR (thanh thuong)) va duong cong van toan cao*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu xanh) or (chinh sach)) - ((thanh tuong) OR (thanh thuong)) va duong cong van toan cao*".
