Perhaps you should try some spelling variations:
hanh trinh » canh tranh, hanh chinh
hanh tranh » canh tranh, hanh trang, lanh tranh
tieu xanh » chieu xanh, dieu hanh, tien anh
tieu danh » dieu danh, tiep danh, thien danh
chua dong » cua dong, ha dong, huy dong
dong cong » duong cong, dung cong, dang cong
cong van » cong vang, cong san, song van
van toan » van tuan, van tan, van thanh
toan ban » van ban

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 ((tieu xanh) OR (tieu danh)) - ((hanh tranh) OR (hanh trinh)) chua dong cong van toan ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((tieu xanh) or (tieu danh)) - ((hanh tranh) OR (hanh trinh)) chua dong cong van toan ban~".
• Adding a wildcard symbol may retrieve word variants: theo ((tieu xanh) or (tieu danh)) - ((hanh tranh) OR (hanh trinh)) chua dong cong van toan ban*.
