Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu tinh, hieu manh
chieu sang » chieu sach, hieu lang, nhieu tang
thien danh » thien anh, thien dang, thien thanh
hanh doanh » hang doanh, chinh doanh, doanh doanh
cong trong » cong thuong, duong trong, cong trinh
doanh cua » doanh luan
trong van » trong cac
ban can » ban dan, ban hang, ban hanh

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 ((((chieu xanh) OR (chieu sang))) OR (thien danh)) - hanh doanh cua cong trong van ban can~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((((chieu xanh) OR (chieu sang))) or (thien danh)) - hanh doanh cua cong trong van ban can~".
• Adding a wildcard symbol may retrieve word variants: theo ((((chieu xanh) OR (chieu sang))) or (thien danh)) - hanh doanh cua cong trong van ban can*.
