Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, hieu manh
chieu tinh » trieu tinh, lieu tinh, chau tinh
thong cong » trong cong, tong cong, thong thong
hanh ban » thanh ban, hang ban, hanh san
va thong » va thuong, va phuong, he thong
dang van » hoang van, hang va
dan van » doan van, dao van, tan van

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 tinh)) - hanh ban va thong cong ((dan van) OR (dang van)) ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chieu xanh) or (chieu tinh)) - hanh ban va thong cong ((dan van) OR (dang van)) ban~".
• Adding a wildcard symbol may retrieve word variants: theo ((chieu xanh) or (chieu tinh)) - hanh ban va thong cong ((dan van) OR (dang van)) ban*.
