Perhaps you should try some spelling variations:
thong cong » tong cong, thong thong, phong chong
hanh tranh » canh tranh, hanh trinh, hanh trang
tieu xanh » chieu xanh, dieu hanh, tien anh
tieu danh » dieu danh, tiep danh, thien danh
tranh van » tran van, trinh van, thanh van
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: theo ((tieu xanh) OR (tieu danh)) - hanh tranh van ((thong cong) OR (trong cong)) san than cap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((tieu xanh) OR (tieu danh)) - hanh tranh van ((thong cong) or (trong cong)) san than cap~".
• Adding a wildcard symbol may retrieve word variants: theo ((tieu xanh) OR (tieu danh)) - hanh tranh van ((thong cong) or (trong cong)) san than cap*.
