Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
nhieu tang » chieu sang, hieu lang, nhiet nang
thanh lap » thanh san, phan lap, thanh hai
cong ban » cong bang, cong tan, cong dan
cong san » cong tac
cong su » cong suc, cong sua, cong cu
su hang » su khang, su dang, su 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: ho ((chieu xanh) OR (nhieu tang)) - thanh cong su hang ((cong ban) OR (cong san)) thanh lap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu xanh) or (nhieu tang)) - thanh cong su hang ((cong ban) OR (cong san)) thanh lap~".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu xanh) or (nhieu tang)) - thanh cong su hang ((cong ban) OR (cong san)) thanh lap*.
