Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, hieu manh
chieu tinh » trieu tinh, lieu tinh, chau tinh
hanh trung » thanh trung, hanh trang, manh trung
dan dung » van dung, tin dung
cong van » cong vang, cong san, song van
van toan » van tuan, van tan, van thanh
toan cao » toan ban, toan tap
ap dung » xay dung, van dung

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: ho ((chieu xanh) or (chieu tinh)) - hanh trung ((dan dung) OR (ap dung)) cong van toan cao~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu xanh) OR (chieu tinh)) - hanh trung ((dan dung) OR (ap dung)) cong van toan cao.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu xanh) or (chieu tinh)) - hanh trung ((dan dung) OR (ap dung)) cong van toan cao".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu xanh) or (chieu tinh)) - hanh trung ((dan dung) OR (ap dung)) cong van toan cao*.
