Perhaps you should try some spelling variations:
chieu xanh » chieu sang, chieu tinh, hieu manh
chieu sach » chinh sach, chiet tach, chieu sang
hanh mang » nhanh mang, hanh trang, nhanh lang
tong cong » trong cong, cong cong, dung cong
cong doan » cong dan, cong hoan, dong doanh
doan phan » doanh phan, toan phan, dan phan
hanh han » hanh nhan, hanh phan, hanh san
phan cau » phan dau, phan cac, phan tu
he tong » he thong, he trong, he cong

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 sach)) - ((hanh mang) OR (hanh han)) he tong cong doan phan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chieu xanh) OR (chieu sach)) - ((hanh mang) or (hanh han)) he tong cong doan phan cau~".
• Adding a wildcard symbol may retrieve word variants: theo ((chieu xanh) OR (chieu sach)) - ((hanh mang) or (hanh han)) he tong cong doan phan cau*.
