Perhaps you should try some spelling variations:
chieu xanh » chieu sang, chieu tinh
chieu sach » chinh sach, chiet tach, chieu sang
thanh tung » thanh cong
hieu manh » hieu nganh, dieu hanh, hien hanh
lang cong » dang cong, bang cong, hang cong
cong dan » cong san, cong tan, huong dan
tung va » trung va, tuong va, dung va
va lang » va nang, hoa lang
ca cau » cua cau, cac cau, can 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: theo ((((chieu xanh) OR (hieu manh))) OR (chieu sach)) - thanh tung va lang cong dan ca cau~.
• Adding a wildcard symbol may retrieve word variants: theo ((((chieu xanh) or (hieu manh))) or (chieu sach)) - thanh tung va lang cong dan ca cau*.
