Perhaps you should try some spelling variations:
chieu sang » chieu sach, chieu xanh, nhieu tang
hieu lang » hieu quang, nhieu tang, hieu van
hanh dang » hanh dong, anh dang, hanh dung
dang hung » dang quang, manh hung, dang cong
hung dung » nhung dung, phung dung, ung dung
cong manh » cong danh, duong manh, cong thanh
cong dan » cong san, cong tan, huong dan
toan cao » toan ban, toan tap

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: ho ((chieu sang) OR (hieu lang)) - hanh dang hung dung ((cong manh) OR (cong dan)) toan cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu sang) OR (hieu lang)) - hanh dang hung dung ((cong manh) or (cong dan)) toan cao~".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu sang) OR (hieu lang)) - hanh dang hung dung ((cong manh) or (cong dan)) toan cao*.
