Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang
chieu tinh » trieu tinh, lieu tinh, chau tinh
hanh trang » thanh trung, canh tranh, hanh trinh
hieu manh » hieu nganh, dieu hanh, hien hanh
dung cong » dung trong
trang va » tran van, hang va
cong tap » cuong tap, cong tac, cong tan
tap doan » tap quan
doan dau » doan dieu, phan dau, doan va
va dung » van dung, va duong, vat dung

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 (hieu manh))) OR (chieu tinh)) - hanh trang va dung cong tap doan dau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((((chieu xanh) OR (hieu manh))) or (chieu tinh)) - hanh trang va dung cong tap doan dau~".
• Adding a wildcard symbol may retrieve word variants: ho ((((chieu xanh) OR (hieu manh))) or (chieu tinh)) - hanh trang va dung cong tap doan dau*.
