Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu tinh
chieu sang » chieu sach, hieu lang, nhieu tang
hanh trung » thanh trung, hanh trang, manh trung
hieu manh » hieu nganh, dieu hanh, hien hanh
trung dap » trung cap, trung dai, trung dam
dung cong » dung trong
dap dung » ap dung, dan dung, dap ung
cong san » cong tac
san than » sang than, san thanh, ban than
than cap » khan cap, thanh lap, thanh cac

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 sang)) - hanh trung dap dung cong san than cap~.
• Adding a wildcard symbol may retrieve word variants: ho ((((chieu xanh) or (hieu manh))) or (chieu sang)) - hanh trung dap dung cong san than cap*.
