Perhaps you should try some spelling variations:
thanh dung » thanh duong, thanh tung, thanh hung
luan nhung » luan chung, luan hung, quan nhung
chu xanh » chu manh, chieu xanh, chua xang
cong dan » cong san, huong dan, cong dong
cong tan » cong tac, cong san, cong thanh
than cau » toan cau, phan cau, than cap
chu van » cuu van, chu han

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 (chu van)) - thanh dung luan nhung ((cong dan) OR (cong tan)) than cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chu xanh) or (chu van)) - thanh dung luan nhung ((cong dan) OR (cong tan)) than cau~".
• Adding a wildcard symbol may retrieve word variants: theo ((chu xanh) or (chu van)) - thanh dung luan nhung ((cong dan) OR (cong tan)) than cau*.
