Perhaps you should try some spelling variations:
thanh dung » thanh duong, thanh tung, thanh hung
luan nhung » luan chung, luan hung, quan nhung
nhung cong » dung cong, thong cong, hang cong
chu xanh » chu manh, chieu xanh, chua xang
cong dan » cong san, cong tan, huong dan
chan cau » can cau, chinh cau, nhanh cau
phan cau » phan dau, phan cac, phan tu

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