Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
choi trong » hoi trong, hoc trong, hoa trong
hoc chieu » hoc thieu, ho chieu, hoc hien
hanh dung » thanh dung, anh dung, manh dung
hanh dong » anh dong, ha dong
cong danh » cuong danh, cong dan, cong thanh

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