Perhaps you should try some spelling variations:
chieu sang » chieu sach, hieu lang, nhieu tang
chieu xanh » chieu sach, chieu tinh, hieu manh
truong cao » truong dai
nhung cong » dung cong, thong cong, hang cong
truong va » truong dai, truong dao, luong va
cong san » cong tac
san chan » san chang, dan chan, san chay
chan cau » phan cau, can cau, chinh cau

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 sang) OR (chieu xanh)) - manh ((truong va) OR (truong cao)) nhung cong san chan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu sang) OR (chieu xanh)) - manh ((truong va) or (truong cao)) nhung cong san chan cau~".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu sang) OR (chieu xanh)) - manh ((truong va) or (truong cao)) nhung cong san chan cau*.
