Perhaps you should try some spelling variations:
nhung cong » dung cong, thong cong, hang cong
thanh toan » thanh hoa, thanh san, tinh toan
danh toan » manh toan, anh toan, dan toan
theo chu » theo chieu, cho chu, chao chu
chu xanh » chu manh, chieu xanh, chua xang
trang va » hang va
tran van » luan van

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chu xanh - hanh ((trang va) OR (tran van)) nhung cong ((danh toan) OR (thanh toan)) cau~".
• Adding a wildcard symbol may retrieve word variants: theo chu xanh - hanh ((trang va) OR (tran van)) nhung cong ((danh toan) OR (thanh toan)) cau*.
