Perhaps you should try some spelling variations:
nhung cong » dung cong, thong cong, hang cong
hanh tang » hanh trang, hanh mang, hanh tung
thanh lap » thanh san, phan lap, thanh hai
theo chu » theo chieu, cho chu, chao chu
chu xanh » chu manh, chieu xanh, chua xang
anh tang » anh bang, anh dang, anh nang
cong dan » cong san, cong tan, huong dan
than cap » khan cap, thanh cac, than cua

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 - ((hanh tang) OR (anh tang)) va nhung cong dan ((than cap) OR (thanh lap))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chu xanh - ((hanh tang) or (anh tang)) va nhung cong dan ((than cap) OR (thanh lap))~".
• Adding a wildcard symbol may retrieve word variants: theo chu xanh - ((hanh tang) or (anh tang)) va nhung cong dan ((than cap) OR (thanh lap))*.
